These are currently checked via: `AC_CHECK_HEADERS([sys/select.h sys/prctl.h sys/sysctl.h vm/vm_param.h sys/vmmeter.h sys/resources.h])`. If we wanted, to we could change this.

I guess this is too fragile to be useful

I guess it could make more sense if someone tried to reproduce this in `rr`.

⚠️ brunoerg opened an issue: "Wallet fuzzing tracking issue"
(https://github.com/bitcoin/bitcoin/issues/29901)
The wallet has poor fuzz coverage. Hopefully, some work is being done to improve it. The goal of this issue is to actively track current work and work that needs to be done to improve fuzz coverage for the wallet.

(https://github.com/bitcoin/bitcoin/issues/29785#issuecomment-2061714375)
I did get a bit of variation but hard to know what's important. `BlockAssemblerAddPackageTxns` was about 10-15% slower on `27.0rc1` vs `26.0`. The bench also throws a filesystem error on 27.0rc1 but completes on 26.0.

Hey,

Just did a quick pass. What is the status of this PR?

💬 murchandamus commented on pull request "fuzz: wallet, add target for Spend":
(https://github.com/bitcoin/bitcoin/pull/28236#discussion_r1569162422)
This comment is inconsistent:

```suggestion
// Add 50 spendable UTXO, 50 BTC each, to the wallet (total balance 2500 BTC)
```

A variable set of available coins might be desirable. Smaller amounts could for example trigger behavior regarding negative effective value or having insufficient funds to create a transaction.

If you removed the Singleton, did you perhaps not push the latest state of this PR?

(https://github.com/bitcoin/bitcoin/pull/28236#discussion_r1569173834)
Agree wtih @maflcko, since the seeds are created per target, it would be better to have a separate target for `CoinsResult`.

💬 maflcko commented on issue "Wallet fuzzing tracking issue":
(https://github.com/bitcoin/bitcoin/issues/29901#issuecomment-2061781675)
Coverage is nice, but if the fuzz test never finds any real user-facing issues, it will be useless. I don't think any wallet fuzz target found a real issue yet? Obviously coverage is the first step toward adding regression fuzz tests, so here are some ideas:

* #23444 tried to add a regression fuzz test, but it was picked up as part of https://github.com/bitcoin/bitcoin/pull/28933, and I couldn't reproduce the regression crash by re-introducing it.
* https://github.com/bitcoin/bitcoin/pull/27

Seems to me that one reasonable path forward is to just do nothing and not
merge these changes.

🤔 glozow reviewed a pull request: "Cluster size 2 package rbf"
(https://github.com/bitcoin/bitcoin/pull/28984#pullrequestreview-2006530259)
I think we had some docs written for doc/policy/packages.md and doc/policy/mempool_replacements.md?

This seems like a merge conflict with #28970, maybe add the fix here instead?

This seems slightly inaccurate, as it wouldn't currently be in a package if `ReplacementChecks` is happening?
