  Huh?  But that's exactly what SO_REUSEADDR is supposed to _prevent_ from
happening.  That's why it's called _REUSE_addr, because it lets you *re-use* an
addr, without getting an error message.  Why would you expect setting it to stop
you from reusing the address?

  Because SO_REUSEADDR works _correctly_ on cygwin, perhaps?

    cheers,
