Class	_Result	Undocumented
Function	_run_with_write_locked_target	Run `callable(args, *kwargs)`, write-locking target for the

def _run_with_write_locked_target(target, callable, *args, **kwargs):

Run callable(*args, **kwargs), write-locking target for the duration.

_run_with_write_locked_target will attempt to release the lock it acquires.

If an exception is raised by callable, then that exception will be propagated, even if the unlock attempt raises its own error. Thus _run_with_write_locked_target should be preferred to simply doing:

target.lock_write()
try:
    return callable(*args, **kwargs)
finally:
    target.unlock()
