The question I have is this: what would be the proper way to fix this?
Personally, I would propose to up the limit of MAX_DEAD_THREADS to the
max number of threads (currently set to 4096)[6], with the rationale
that if you can create 4096 threads, you should be able to join them
after they're dead. I know that you can still hit the limit if you
create more threads after some of them ended, but it sounds like a
more sensible constraint. Any thoughts?
I think it would make sense to to eliminate |MAX_DEAD_THREADS entirely
and just use sMaxThreads, though we could go even higher since extremely
long-running highly threaded applications can potentially blast passed
any limit we set... 32 seems absurdly low in any event.
The comment about sMaxThreads being arbitrarily set is also something
that should eventually be remedied, though 4096 is probably good
enough... for now.
