awt and one other thread stuck in Win32FileSystem.canonicalize() method doing native OS IO operations. not really a high amount of calls being done (single digit, likely 4)

likely another application starved the IO resources on the computer. Not much that can be done IMHO on netbeans side, the AWT thread affected code is not doing anything terribly wrong. I don't see reason enough to rewrite it.
