When trying to debug bash with its debuginfo installed, the Debug Window takes an inordinate amount of time to come up, 20-30 seconds on a 2GHz/1GB memory x86 machine running F7.
This has been somewhat mitigated because now the only sources parsed are the ones in the current frame. Some more may need to be done later as large sources are still a little slow. Adding the info to the JDOM seems to be the slowdown. Specifically, adding the lines.
