[Glass] debugging zinc server requests/responses with tode or GemTools

Hi guys,

Thanks for the feedback. I got it sorted out.  

Prior to seeing Marten's advice I changed
ZnSingleThreadedServer>>#handleRequestProtected: to:

 ^ self authenticateAndDelegateRequest: request

Which bypassed Zinc's server error handling.  I then ran the server from
within tODE but the session kept getting disconnected without doing
anything.  The gem logs from when I was running the server in a Gem (on the
same port as in tODE) and restarting it with daemontools showed: 

'(error 2719) process with this cache name already exists'

which would cause a "Fatal Smalltalk Stack Underflow, SEGV in StackLimit

I was able to track down the Zinc server with the process and 'terminate'
it.  Once that was done the blocking server in tODE would run and I was able
to fix my bugs.  So I'm all set.

I'm not sure what I did to the server when it was running in the Gem to
leave the process hanging around in the Stone.  I'll wrap the code I use to
start/run the server in an #ensure: to attempt to make sure it stops if
things are crashing.

and was able to fix my bugs.
