Clean IDE build, clean user dir, invoked Open project. The operation was slow (due to high filesystem contention,
external to the IDE), but a thread dump revealed several (6 from L&F + 2 ours) threads trying lo list the folder.
I believe those 6 "Basic L&F File Loading Thread" are wrong (only one folder is listed using single filechooser).
Needs investigation, thus assigning to performance
Hmm, there is something dirty probably.

Should be fixed along with 179124 fix, there was several unneeded requests for rescanning current directory which I eliminated.
