Display the Thread.Mutex that a Thread.MutexKey belongs to also when disconnected.
When a Thread.Condition
is waiting, the Thread.MutexKey
that it displays has typically been disconnected and no longer shows which Thread.Mutex
it belongs to (Pike 8.0.1206):
-:1: _static_modules.Builtin()->condition()->wait(MutexKey())
Also fix the rendering of Thread.Condition
to display Thread.Condition
and its associated Thread.Mutex
(if any).
