Countless (probably around 100) git processes running

This... shouldn't be as expected... should it?

Also when running sourcetree my computer is acting incredibly slow.

I've tried restarting SourceTree and restarting my computer and the list keeps building up over time, gradually getting slower to the point that something like staging a file / hunk takes about 12 seconds to process / update the UI.

I am running:

• Version 2.3.5.0 
• System Git version 1.9.4-preview20140611

Update: Same thing for 'Console Window Host' and 'sh.exe'

Update 2: Closing all instances of git via `taskkill /f /im git.exe` will cause Source Tree to crash so presumably these are caused by Source Tree and not some other software.

Update 3: Closing all instances of git via `taskkill /f /im sh.exe` seems to fix any freezing issues Source tree has (and causes elsewhere)

Update 4: Changing git to embedded and updating the embedded git seems to fix this issue
