This issue is observed across multiple targets in the test farm. With both
timer1 and signal3 tests.

--- Comment #3 from John Dallaway <john@dallaway.org.uk>  2009-03-23 10:41:27 ---
The underlying issue is readily observed in the POSIX timer1 test. Both thread1
and thread2 wait indefinitely at the call to pause(). This issue was introduced
with the following change:

    2006-07-18  Jonathan Larmour  <jifl@eCosCentric.com>

    * src/signal.cxx (pause): Although already POSIX compliant, if we wait
      for all signals, behaviour is more Linux-like.

The patch fragment for pause() in signal.cxx revision 1.19 looks like this:

         // Check for any pending signals that can be delivered and
         // if there are none, wait for a signal to be generated
    -    if( !cyg_deliver_signals() )
    +    while( !cyg_deliver_signals() )
             signal_sigwait.wait();

    -    // Now check again for some signals to deliver
    -    cyg_deliver_signals();
    -    
         signal_mutex.unlock();

It would appear that the POSIX tests are not written to accommodate the more
Linux-like behaviour implemented by this change. I have verified that signal1
(ref Bugzilla 1000689), timer1 and signal3 all PASS on target 'psim' when this
change is reverted.

--- Comment #4 from John Dallaway <john@dallaway.org.uk>  2009-03-23 10:52:42 ---
Andrew/Nick/Jifl, should we fix the various POSIX tests to accommodate the
revised behaviour described in the ChangeLog entry in comment #3 or should we
revert the change of 2006-07-18?

If the revised behaviour is desirable, someone needs to volunteer to fix the
tests.

If I don't hear from anyone, I will revert this change.

Workaround checked in to the repository trunk and eCos 3.0 branch. If a more
Linux-like behaviour of pause() is desirable, the POSIX tests should be updated
to accommodate this.
