Hi,
It seems that even when in linux-os.c we test if futex'es work and we set linux_no_threads_p accordingly, something is calling futex_wait never the less. As the futex calls do _NO_ error checking this means the system then goes into a loop trying to call the futex call that fails over and over again.
That's strange. I have a 2.6 kernel, but replacing futex_wake body with "return 0;" and futex_wait with "for(;;);" didn't give me problems. There are two calls to futex_wait: get-mutex calls it if the mutex is not available (should not happen and thus ok to loop if there is only one thread), and condition-wait which I think is similar.
So: is 2.4 support dead or is this a bug?
Tell us how to reproduce it and what is the observed behaviour.
Groetjes, Peter
