I'd definitely try again with 1.2 or master, as there have been at
least some improvements re: using as a library, as well as bugfixes.
If it still fails, I'd be interested to know how. Threading is a bit
sketchy as Fabric relies heavily on shared module state right now
(this is one reason parallelism is using multiprocessing) but your
problem *could* conceivably be something else.

Technically, yes, but I still haven't merged the (ongoing, this week)
work for multiprocessing from its feature branch (so 'master' is
currently 1.2.2 + bugfixes). Said feature branch is:


I'll be announcing here on the list when I merge that into master,
though an actual release of 1.3 will probably follow that pretty
quickly so I might jump straight to that :)
