[Interest] all of QtBase depends on qregexp.cpp (or almost)?

Maybe if I had a lot of time and those files were made for human consumption ;)

BTW, reason I touched the file is that under certain conditions I'm seeing 
crashes or hangs on exit when the QRegExpEngine cache is taken down. I was 
hoping to be able to check if there's an atexit order problem (which I surely 
must be causing myself). No such luck, but my issue does go away when I disable 
that cache.

Is there any recent data on how important that cache is, performance-wise? (And 
I mean just the cache, not the other optimisations.)
