          Issue ID: 18621
           Summary: core.sync.condition notify methods cannot be used from
                    a (unix) signal handler
           Product: D

Using core.stdc.signal I can set up a signal handler to handle SIGINT (^C),
however signal handlers have a limited set of things they can do.  The handler
must be nothrow and  nogc.

pthread_cond_signal and pthread_cond_broadcast are safe to call in a signal
handler and typically used to trigger shutdowns, however core.sync.condition
has no safe method that can be called to notify or notifyAll.

Would it be possible to add a "nothrow  nogc" safe version of these methods
that return an error code instead of throw so that core.sync.condition can be
used in a (unix) signal handler?  Thanks.
