You can execute blocking call at any time of your pleasing. It will
predictable block all execution paths. Typical wrapper around blocking calls
is thread. Something like this (from
http://twistedmatrix.com/documents/current/core/howto/threading.html):
d = threads.deferToThread(yourSyncCall)
d.addCallback(...)
