Pause MATLAB in OS X

A bash script to pause MATLAB, allows a hot key

I use this script to pause and continue MATLAB at the Unix process level using the kill -STOP and kill -CONT commands.
Combine it with Quicksilver and you can assign a key combination that will pause the running of MATLAB at any time. It is superior to other methods because it requires no overhead or listening on MATLAB's behalf.
Should work in any linux OS (may need to change awk to nawk), to install:
- copy script wherever
- chmod u+x /path to script
- run script with key combination using Quicksilver
