Git Extensions: Win32 error 487: Couldn’t reserve space for cygwin’s heap, Win32 error 0

Cygwin uses persistent shared memory sections, which can on occasion become corrupted. The symptom of this is that some Cygwin programs begin to fail, but other applications are unaffected. Since these shared memory sections are persistent, often a system reboot is needed to clear them out before the problem can be resolved.
