The problem you're experiencing is because GNUstep's runtime creates
threads with a detach state of PTHREAD_CREATE_JOINABLE, which don't
release the resources associated with the thread until another thread
calls a pthread_join() on the terminated thread in order to collect its
return status. Which is kind of a bug in GNUstep, because you have no
way of joining it manually.
Your best bet is creating the thread manually, not using the NSThread
API. I use the following code snippet to do the trick:
pthread_t thread;
pthread_attr_t attrs;
if ((code = pthread_attr_init (&attrs)))
{
// Error initializing thread attributes
}
if ((code = pthread_attr_setdetachstate (&attrs, PTHREAD_CREATE_DETACHED)))
{
// Error setting thread attributes
}
if ((code = pthread_create (&thread, &attrs, ThreadFuncCallback, NULL)))
{
// Error creating thread
}
This has worked for me with thousands of threads being created and
terminated.
