Just a quick question before I commit this version: is the filename generated
by mktemp guaranteed to be in a directory the user has write access to? If
not, an IOError exception could be triggered when trying to actually write to
the file, couldn't it? That's about the only thing that I can think of to
keep the try blocks in there. But I'd prefer it if you are right, because it
would save a double try in the code.

Nice. When you get a chance (zero hurry) and this settles, I'd like to
include a bit more info about this both as links on the webpage, and as a
short section in the manual. Basically the relevant links and some brief
instructions Windows users (both with and without cygwin) can follow to use
your tools in conjunction with ipython.
Thanks again for your work,
