Take care.. UX-domain sockets are bidirectional, pipe(2) is not.
Although it is -internally- implemented similarly, pipe intentionally
only connects the sockets in one direction, not in both, descriptor
permissions are set for FREAD and FWRITE respectively, not
FREAD|FWRITE in both.  Contrast this to how socketpair() is
implemented (that one IS bidirectional).
