User Comments:
wadechandler: I had opened about 13 Maven NB RCP and Java projects. I expanded the packages in one of them. I selected 9 files. I right clicked on those files. My mouse rolled over the History and Mercurial menu items. One of them stayed highlighted. The IDE had a progress bar stating it was background scanning when I did this. The IDE froze for nearly 30 seconds.



Maximum slowness yet reported was 27908 ms, average is 26955

Well, it's not blocked by any I/O or a mutex, it's simply matching file paths against hgignore patterns in memory. There are three threads doing the same job and the AWT thread seems to share resources with the other two, but i would guess the AWT should have a higher priority, don't know.
BTW how many records do you have in your .hgignore file?
