failure rather than punting to wait_sig.
* miscfuncs.cc (low_priority_sleep): Accept INFINITE sleep to mean "don't reset
the priority after setting it to idle".  Return previous priority.

Christopher Faylor 6597785dc2 * exceptions.cc (setup_handler): Add debugging output. Set thread priority to
idle if pending signals to allow other threads to get into interruptible state.
* miscfuncs.cc (sys_mbstowcs): Save current thread in variable to avoid an OS
call.
* wait.cc (wait_sig): Reset thread priority each time through loop since the
priority may have been set down to deal with pending signals.
