Before I commit anything, let's decide on that one.  Weave used to
print 'None' whenever it compiled anything, I changed it a while ago
to the current 'weave:compiling'.  I'm also of the opinion that
libraries should operate quietly, but with weave I've always wanted
that message in there.  The reason is that when weave compiles (esp.
with blitz in the picture), the execution takes a long time.  The same
function goes from miliseconds to 30 seconds of run time depending on
whether compilation is happening or not.

This difference is so dramatic that I think a message is justified
(absent a proper logging framework).  It's helpful to know that the
time is going into c++ compilation, and not your code hanging for 30
