Delete your temp files

[Dain Sundstrom <ds...@gluecode.com>]

Part of the deployment system rewrite was an effort to clean up our 
handling of temp files.  I carefully went though our entire active code 
base (1) searching for places where we create temp a file or directory, 
and added code that explicitly deletes the file or directory.  Since we 
are writing a server that could run for months (assuming we get 
everything right), we can not rely on the VM's deleteOnExit for files 
and we have no such hook for temp directories.  Right now there should 
be no place, including test code, where we leave a temp file.

This change was long and tedious, and I don't want to have to do it 
again, so please please please be careful to delete your temp file as 
soon as possible after creating it.
