Well, I actually want/need it now.  As I stated before, I have the C
code to make use of the door library, but for stat-like functions, I
have to copy the code from file.c, which not very DRY.

Have we convinced Dan yet?  :-)

Oh, by the way, Google gave me this link:
http://smarden.org/socklog/readme.solaris.html
which states that /var/run/syslog_door was introduced with Solaris 8.
Before that, syslog used /etc/.syslog_door.
