Bug 189720

When a developer swaps out of the IDE to another project/program/debug/etc..., the only files NetBeans really needs to immediately know about with regards to changes are the files which are opened in the IDE.

Any additional files will be refreshed/updated upon opening in the editor, building with Ant, running, debugging, etc...

At present, within the 6.9.1 IDE, I have 10 projects open.  7 JAR projects.  2 EAR Projects, and 1 JavaFX Project.  The only file I have open is the main frame/stage file for the JavaFX Project.

When I swap out to check EMail or IM and return to the IDE, the system immediately starts checking all 9850+ files in the 10 projects (about 5 minutes processing time).  During this check, the compilation/debugging of the JavaFX file is delayed due to either a lack of resources (like CPU hogging), or a block until the process is completed.

The check needs to happen in 2 phases.  

Phase 1 is to check the open files.  This needs to be quick and should be doable for the limited number of files NetBeans can hold open in a matter of seconds.

Phase 2 is to check the closed files.  At present, the only reason I can envision doing this is to update any icon flags for revision control or similar reasons.  This should be run at a lower priority in the background.
