With the abort out of the picture, I notice that after launching Git GUI,
Emacs is consuming 100% of one CPU core.

Simplified recipe:
  (async-shell-command "c:\Program Files\git\cmd\git-gui.exe")

Presumably this also happens for programs other than Git GUI.
It isn't caused by your recent change (was already present before).
