The I/O error as such might be related to the win7 /
cygwin combination requiring more retries or such.

I.e. they disabled the background process that will
open the working copy soon after the OS detected
some file change. The scan itself may take a very

may get opened at some very inconvenient time
while the commit is still in progress / in some critical
stage.
