Tried out Sublime Text 2 Win 64 Bit (2139)
While using it i felt the system behaved a little more clogy than usual. After checking the task manager i saw that ST 2 had over 2 million page faults. (http://en.wikipedia.org/wiki/Page_fault
Finding that quite strange i restarted ST2 and the number of page faults was quite reasonable. The instant i started scrolling a simple plain text file (also just 1 tab), the number skyrocketed. I can't think of any reason this should be normal, the only program that i got running that get close (or above) to that number is my anti-virus program and Steam.
Also, it does not only apply to scrolling. Just letting the program idle in the foreground has the same effect, but not so profound.
possible page fault leak in win 64 bit version of Sublime Text 2.
also happens with the 32-bit version (2139)
