I hadn't tested with any musl version but 1.2.1. A quick test with
1.1.24 shows that it didn't hang then, but hit the same segfault if
using perl without a fixed thread stack size.

The only reason the segfault seemed new to me was because the program
had never reached past the hang in the futex syscall :)

I will see if I can find the time to write some programs to torture test
the impl further, assuming that would help.

Cheers,
Érico
