Hmm ... the other thing that I just remembered is that I first noticed
this problem on 1.7.5-1 on Win7, and the thing that made me suspicious
was that replacing the offending command with:

	strace rm -f -r ...

made the command suddenly work! But ...

	sleep 1 ; rm -f -r ...

failed in the same way  :-(

I haven't tried reproducing this particular behaviour on 1.7.7 (yet).
