    <tschwinge> pfinet: /build/buildd/hurd-20080607/build-tree/hurd/libports/create-internal.c:115: _ports_create_port_internal: Unexpected error: (ipc/mig) wrong reply message ID.
    <neal> it would be nice to print out the id when those sorts of errors occur.

This error code is `MIG_REPLY_MISMATCH` and can be returned in GNU Mach's
`kern/exception.c (exception_parse_reply)`, in MIG-generated code, see `user.c
(WriteCheckIdentity)`, and in glibc's `sysdeps/mach/hurd/ioctl.c (__ioctl)`.
