   Hello,

   I ran into this problems a few months back. After looking into 
gedit's source code, I think it has to do with the way gedit embeds 
python (you can check out http://www.linuxjournal.com/article/3641, 
among others). There should be a way for gedit to release the 
interpreter lock once in a while, but I haven't gotten a chance to get 
into this yet.
   IMHO this is actually a worthwhile problem to look into. Without 
solving this, other build-like tools (e.g., the LaTeX plugin) which use 
Python will simply not be viable alternatives to dedicated IDEs for the 
same purpose.

   Bye,

   Ami
