I looked at this library a few years ago before I wrote my own (for a
windows system), and the big problem I saw with it was that it uses
fibers on windows.  Fibers have this little problem, if you say you
need, say, 20kb for the fiber stack, it still allocates as much memory
as a thread uses (4megs by default I think), meaning if you try to
create 10k of these little buggers, you run out of memory well before
that.  Made this library rather worthless for my use.  If it really
wants to be used for a good coroutine based paradigm, then they need
to get rid of the fiber usage on the win32 side.
