In short command-line scripts, it's often much easier to block, especially
if the script doesn't need to do any serving. However, Twisted's API is
always non-blocking, returning deferreds. Here's a short function that
allowes more natural usage from scripts:
succ, fail = , 
d.addBoth(lambda _: reactor.stop())
Here's a short usage example:
>>> from twisted.internet import defer, reactor
>>> def callIn10():
... d = defer.Deferred()
... reactor.callLater(10, d.callback, "hello world")
... return d
>>> import time
>>> print time.time();print makeBlocking(callIn10());print time.time()
This is especially useful in scripts which want to do pb calls, as currently
there is no way to do pb calls in a synchronous manner.

Buffy: I don't like you hanging out with someone that... short.
Riley: Yeah, a lot of young people nowadays are experimenting with shortness.
