Rsync on Cygwin testsuite results

[Max Bowsher]

I hacked config.h to undefine HAVE_SOCKETPAIR. Cygwin's socketpair was
failing randomly, causing errors on roughly a third of testsuite runs.
Having made that alteration (so rsync was using pipe, not socketpair), I ran
the testsuite 100 times. SSH tests were not enabled.

Out of 100 runs, 4 hung on the "daemon" test. The remaining 96 passed or
skipped all tests.


So - one lurking hang, one problem (with socketpair) with an easy
workaround.

Not too bad really, if I can make any further headway in tracing that hang.

Max.
