Yes, it used device_write. I have changed it to use device_write_inband
with the result that my programm crashes:
gauss:/mnt/newton/cache/hurd/oskit-mach-debug# ./xmit -r eth0 192.168.2.3
xmit: xmit-test.c:268: xmit_demuxer: Unexpected error: (os/device) invalid IO
size.
Aborted
Ah, before the recent bug fix (OSENV_NONBLOCKING), the program stopped
here also. It seems that that my buggy program triggers many other bugs to.

... so device_write doesn't check correctly all passed parameters?
