[chimera-dev] event loop

[Greg Couch]

Use the (Tcl) event loop.  If you run the interface in a separate 
process, then you have chimera's event loop invoke a callback when there 
is data to be read on the socket connecting the two processes.  That is 
what's done to implement the --send command line option.  See 
DBPuppet/tcl_sockets.py for details.

An alternative would be to use threads where the queue is checked every 
frame.  See ReadStdin/__init__.py for details there.

     HTH,
