I think the new attached patch shows that, but I'm not an expert.

POSIX calls to glibc are re-routed to the Hurd servers. Some of the Hurd severs
depend on GNU Mach, while other Hurd servers depend on other Hurd servers.
+The graphic below demonstrates this. In the picture glibc's send(), which is an
+RPC handled by pfinet, which uses a device_write RPC to actually emit an Ethernet
