Windows, EAP 8995
1) Open a maven project
2) IDEA will read pom files in the background for quite a long time (this seems to ignore the setting "Maven | Importing | Import in background")
3) Editing during this period is not pleasant because it's completely hit-or-miss whether completion will be available, so I prefer it to be a foreground task that I can move to the background if desired
4) Trying to run an application debug while the background task is running causes a softlock. It appears to make very slow progress, but I've never been patient enought to allow it to complete, because it takes > 30 minutes at least.
