This is probably unrelated, but who knows - since it just happens after installing Xcode 4.5, and usually, here are the experts ;)
So, any help is appreciated!
When attempting to open a Terminal window with a bash shell, the new console window "stalls" for a significant time, say 20 seconds or so until it eventually becomes ready. This will also affect other Terminal windows and also programs trying to read from disk, which stall as well (for example Mail when trying to read from disk).
It might have to do something with ASL, and maybe also with the fact that overnight the disk usage shrinked by about 25 GByte (some cron task or Xcode removing old stuff?)
Here is a sample gathered with Monitor app:
