The sub-process was diff, I was running `M-x diff-backup RET' on
w32proc.c and waiting for it to finish, than running it again.  I just
checked the source for diff-backup and it seems that it runs diff in
async mode.  Since I just looked at the *vc-diff* buffer, it is
possible that one run of diff overlapped over the next one.  So
probably I had three parallel processes running, or at least
reader_thread did not terminate before the next process started.

This is a good explanation

All this was done with allocate_heap starting the request at 2GB.
As I mentioned in a previous email, this ended up with approx 1.8Gb
being reserved for the heap.

Thanks for helping me out.
