This commit fix games hanging because of my prior Revision c2e6fdf09f

Browse Source 
The external exceptions in dolphin are checking frequently but is different to real HW, so sometime the game is in a loop checking GPU STATUS, the exceptions doesn't checked, and the game hang.\
For solve this I need a trick: still waiting for the exception handler be linked but if CommandProcecsor is reading the GPStatus, resume this.

This fixed "TimeSplitters: Future Perfect" broken in the Revision c2e6fdf09f and surely others games.
