Yeah, I know. Send it to the list. Anyway, I regularly end up
 forgetting to change the permissions on Cache, Sessions, Logs, and
 ErrorMsgs. Invariably, I get this traceback in the error_log:

Traceback (most recent call last):
  File "/var/opt/sb/m2tmp/webware/WebKit/AppServer.py", line 184, in
loadPlugIn
    willNotLoadReason = plugIn.load()
  File "/var/opt/sb/m2tmp/webware/WebKit/PlugIn.py", line 72, in load
    os.mkdir(cacheDir)
OSError: [Errno 13] Permission denied:
'/var/opt/sb/m2tmp/appdir/Cache/MiddleKit'
ERROR: Plug-in /var/opt/sb/m2tmp/webware/MiddleKit raised exception.

Now, note that, in addition to the basic barf, it's barfing a second
 time because it can't write the barf to ErrorMsgs. My suggestion is
 twofold:

	1) Make sure you dump the exception to the browser regardless of
	whether or not you can write it to ErrorMsgs / Logs

	2) When you detect "permission denied" for any of those four
	directories, give an explicit error page that says "hey, dummy, go
	set the permissions correctly on those dirs".
