Sorry, but I still can't reproduce it.  Again, more than 1000 iterations
on my W7 box.

Just to be really sure I ran this on a Vista SP2 machine, like you, with
Cygwin 1.7.0-57 and the latest bash, svn and ssh packages available from
the 1.7 release area OOTB.  >1500 iterations, no problem.  

If I were you, I'd definitely try to investigate if there isn't some
software on your machine acting as BLODA.  The strace looks suspicious.
