  getpeername is part of SUSv3 and Windows also provides the function
as part of winsocks.

getpid is also provided by both Posix and windows and we do not even
use getpid on Windows since we rather call GetCurrentProcessId.

"because it makes sense" (we discussed this on IRC, and I couldn't
find anything in my software museum that has no getpeername() - not
even SCO Unix! - and checking for getpid() borders on ridiculous...)

Stared-at-patch, test compiled on Linux.

Your patch has been applied to the master branch.
