thanks for the helpful response.
the redirection stuff doesn't work too well when called from java. see
a quick scan of the 2.6.3 sourcecode showed that i could just have
is_a_socket return false (0) in all cases. only downsides i could
determine were inability to run from inet and avoiding some cleanup
code--which avoids sending a tcp RST--beneficial to winblows when rsync
with this modification, rsync seesm to work fine in my application.
does anyone see a problem with this modification, assuming the resultant
binary would never be run in any mode except daemon mode?
