Well, I forgot, there's at least an issue with svnserve. I got that
in the past, and could reproduce it: once I kill the svn client
with Ctrl-C and kill the SSH master too, the sshd terminates, but
svnserve is still running, and now has 1 as its PPID:

UID PID PPID C STIME TTY TIME CMD
vlefevre 48724 1 0 12:40 ? 00:00:00 svnserve -t

If svnserve was waiting for something from sshd, it should at least
have noticed that the connection is no longer there.

lsof still shows:

svnserve 48724 vlefevre cwd DIR 0,32 4096 110673531 /home/users/vlefevre (...:/forge_home)
svnserve 48724 vlefevre rtd DIR 254,0 4096 2 /
svnserve 48724 vlefevre txt REG 254,0 86256 9413 /usr/bin/svnserve
svnserve 48724 vlefevre 0r FIFO 0,8 0t0 957950313 pipe
svnserve 48724 vlefevre 1w FIFO 0,8 0t0 957950314 pipe
svnserve 48724 vlefevre 2w FIFO 0,8 0t0 957950315 pipe
svnserve 48724 vlefevre 3r CHR 1,9 0t0 7109 /dev/urandom

BTW, is the permanent open of /dev/urandom normal?
