I didn't mean to confuse, just throwing some ideas out, sorry.
Here's the big picture:
A function is called, which creates a Submission object, and then calls
a sequence of methods on it. Since this is a normal everyday function,
the user must wait for it to finish. So after some basic integrity
checks, it creates a new thread to do the major processing, which could
take a significant amount of time. Once that thread is created and
started, the function the user called returns, and the user goes on
their merry way. The thread from which the user originally called the
first function should end shortly after that, but as always with
threading, no guarantees.
Well, I've found the problem. My own oversight, a NameError in the top
level except block, I forgot to qualify the name of the Exception being
caught. I should have used pychecker, I have no excuse not to have,
it's installed. Sorry to have wasted the group's time, but I have
learned from this greatly. Nothing like complete embarrassment in front
of one's peers to make a lesson stick. ;)
