POSIX: allow WaitableEvents to be deleted while watching them.
On Windows, one can close a HANDLE which is currently being waited on. The
MSDN
documentation says that the resulting behaviour is 'undefined', but it
doesn't
crash. Currently, on POSIX, one couldn't use WaitableEventWatcher to watch
an
event which gets deleted. This mismatch has bitten us several times now.
This patch allows WaitableEvents to be deleted while a WaitableEventWatcher
is
still watching them. It applies only to watchers, the usual Wait() and
WaitMany() calls still require that all their target be valid until the end
of
the call.
