SQE asks to store a prefs key in a project, which then waits for the project lock. This is held for a long time by a Java EE project's view, parsing some Glassfish config file; the Windows file system is taking a very long time to respond, perhaps due to lack of working memory.

The root slowdown is probably just the usual crappy Windows I/O performance, but the blocking of the GUI is due to AuxiliaryConfigBasedPreferencesProvider trying to write out new values immediately. Unless flush() is called, it is permitted to do so asynchronously, though this could result in some race conditions.
