I think, that it doesn't hangs in PHP CC, it seems quite OK for me...but maybe something strange in Parsing API? Tomasi, what do you think?
Comment 3 Tomas Zezula 2012-03-26 17:07:43 UTC 
There is a problem with FileSystem's recursive listener.
It's not multi threaded and it takes ages, I think I am able to eliminate this call for code completion thread.
Comment 4 Tomas Zezula 2012-03-26 17:51:08 UTC 
The funny thing is that the slow FileUtil.addRecursiveListener does file crawling. The issue is reported on Win32 and XNU where it's in fact not needed as the OS provides recursive file events.
Comment 5 Tomas Zezula 2012-03-26 17:54:27 UTC 
As I am not able to do anything with the FileUtil.addRecursiveListener I at least removed the need to call it.
It still may slow the code completion a bit when called concurrently to code completion but it does not block it.
