I've got a few reports of this but I'm usually unable to reproduce
it on my OSX with both blead and 5.8.8 IIRC. I'll try again in case
I've missed something.

If you can isolate the case and correct it, it will be appreciated :)

There are cases where it makes sense; for example the stream tests
usually fail on Linux and Cygwin, so I've added some skips there
(because stream is usually not implemented on those systems). But in
the case of the UDP failures on OSX, I suspect a bug in OSX or in the
way the UDP mechanism works. OTOH, stream and UDP are not the mechanisms
one should use: Sys::Syslog since version 0.15 supports native Unix
syslog(3) calls and will support Win32 event log in the next version
thanks to Yves Orton. You can test it from here:
