We are using blockCallFromThread, which is very different from
callFromThread.  But, blockingCallFromThread does block.  It basically
lets you call a twisted using/deferred returning function and block
for the result.  This allows you to run twisted in a thread, but
create blocking interfaces to twisted using things that are in turn
usable from ipython.
