Found a note from Martin Koeppe from about 13 years ago which
mentioned the format of FIFOs in Windows's older 'Service for Unix'
format (cifs.ko enables this by mount option 'sfu'). The other parts
of this (device and char files for examples are implemented in
cifs.ko's 'sfu' mount option), but not FIFOs.
Excerpt from Martin's note follows:
---------------------------------------------
addressing the "missing feature p)" in TODO, I found out,
how special files are stored by SFU/Interix. It's rather simple,
and no extended attributes are needed. You can (theoretically)
create such files with simple DOS commands.
1. FIFOs:
If a file has 0 bytes and has the System attribute set,
Interix considers it as a FIFO special file.

Wonder why we implemented the other parts of this (in cifs.ko) but not FIFOs?
