Upon further investigation (ok, trial and error...), it seems that using
the multipart form encoding, in conjunction with CGI.pm (I'm using
CGI.pm-2.49) and Apache::Session, causes my test script to hang
at the "op" function within the IPC modules.
In the same test script, if I use the Apache::Request object instead of
the CGI object, the script runs fine, and Apache::Session works fine
(with either form of encoding).
I will be upgrading CGI to the lastest rev to see if that fixes things.
