[Bug-gnubg] multithread closing bug

[Christian Anthon]

Hi Jon and others,

most of the time when I close the mt version I get the following error on exit

GThread-ERROR **: file gthread-posix.c: line 171 (): error 'Device or
resource busy' during 'pthread_mutex_destroy ((pthread_mutex_t *)
mutex)'
aborting...

with the corresponding back-trace

#0  0x0091a402 in __kernel_vsyscall ()
#1  0x437a9f30 in raise () from /lib/libc.so.6
#2  0x437ab781 in abort () from /lib/libc.so.6

It is as far as I can tell always the line (521)
FreeMutex(td.queueLock);
that causes the problem. A g_usleep(1000) (that is 1ms) added just
after MT_CloseThreads, seems to cure the problem.

Not a very serious problem obviously, but it might be an indication of
a more fundamental problem.

Christian.
