Hello John,

I guess you mean pthread_detach()? I never thought that that was
needed, and reading the man pages suggests that it's equivalent to a
non-blocking version of pthread_join. So pthread_join should
theoretically do the same cleanup that pthread_detach does, after the
child thread exits. And indeed, calling pthread_detach after
pthread_join (or vice versa) still leaks memory. pthread_detach
returns an error too (ESRCH), as I guess it should.

Not sure what to do now, I suppose I'll modify my program to keep a
thread pool around so this won't matter. Thanks for the help though.
