Hi --
I'm running into a "Too Many Open Files" IOError 24 when looping through several hundred calls to a website. I'm calling twill via the Python API directly, and it looks like it is getting hung up inside mechanize and subprocess calls. Is there an upper bound on how many times you can call twill from within the same interpreter? Or are there explicit calls to make to close or otherwise clean up after a particular twill session / subprocess call?
Thanks!
Ramon
