[ECOS] Mutex assertion fail when select() timeout

["I-Jui Sung" <ijsung at csie dot nctu dot edu dot tw>]

Hi eCos folks,
    According to James Chen's early post, the following code will throw an
assertion on timed-out mutex in
kernel/current/src/sync/mutex.cxx.

=testing code=
#include<stdio.h>
#include<sys/select.h>
#include<sys/time.h>
int main(void)
{
        struct timeval tout;
        tout.tv_sec=0;
        tout.tv_usec=1;
        printf("Before select\n");
        select(0, NULL, NULL, NULL, &tout);
        printf("After select\n");
}

P.S.    The attached file is a patch suggested by Chen.

Happy hacking,
I-Jui Sung
