Bugfix 

With 2000 CTTR never finished checking memorystick on my laptop (core i3 2.2ghz sandybridge) if i have a save data, because the shutdown Status hasn't changed/completed at the time the game call the next sceUtilitySavedataInitStart (the status still SCE_UTILITY_STATUS_SHUTDOWN because it's taking too long to became SCE_UTILITY_STATUS_NONE)
so i couldn't even get to main menu on CTTR with 2000 unless i deleted all CTTR savedata

With 1500 i didn't get any problem on other games, but i don't have many games to begin with, 
however there are people in ppsspp forums (Multiplayer thread) tested my builds which also have (these commits) on many games without memorystick issue

Here is screenshot using win32 build at orphis:
