KDevelop holding on to large chunks of memory

[Nick Savoiu]

Here are the top values for step 5 and 10 for another project:

  PID USER     PRI  NI  SIZE  RSS SHARE STAT %CPU %MEM   TIME COMMAND

29873 nick       9   0  657M 656M 26232 S     0.0 32.5   0:36 kdevelop
29922 nick       9   0  142M 142M 25912 S     0.0  7.0   0:15 kdevelop

This is what top reports right after "Updating..." finishes.

Also, on an empirical note, it takes roughly 15 seconds to close KDevelop in step 6 whereas it takes only 2 seconds in step 11. This tells me that most of those pages are used and not just allocated virtual memory.

Additionally, KDevelop crashes every other time when I put it through step 3 but I don't have a valid trace. Anything else I can do to debug it?

I guess the most immediate thought is.. how do you know?
