[3.4] Fix deadlock on th->interrupt_lock after fork

2026-03-07T04:41:44+00:00

[Bug #21860]

If a thread was holding this lock before fork, it will not exist in the
child process. We should re-initialize these locks as we do with the VM
locks when forking.

Extend the timeout of fork-exit bootstraptest

It often fails randomly.

http://ci.rvm.jp/results/trunk-yjit@ruby-sp2-noble-docker/5421564
```
 Fstderr output is not empty
   bootstraptest.test_fork.rb_78_287.rb:16:in 'block in ': failed (RuntimeError)
           from :257:in 'Integer#times'
           from bootstraptest.test_fork.rb_78_287.rb:10:in ''
```

I'm not sure why the frequency of failure has suddenly increased,
though.

Re-initialize vm->ractor.sched.lock after fork

2024-08-13T18:52:24+00:00

Previously under certain conditions it was possible to encounter a
deadlock in the forked child process if ractor.sched.lock was held.
