According to this article about the /proc filesystem, "the number directories 
are running process information by PID."

So /proc/5/fd has to do with whatever process is PID 5.  On my RaQ 4, that's 
mdrecoveryd:

[root /root]# ps -f -p 5
UID        PID  PPID  C STIME TTY          TIME CMD
root         5     1  0 Apr13 ?        00:00:00 [mdrecoveryd]

A quick Google for mdrecoveryd reveals that mdrecoveryd is a "dummy process to 
handle the recovery of threads"

Now on my Fedora box, mdrecoveryd is running on PID 8. But when I try to look 
at /proc/8/fd there is no apparent issue with that:

[root@localhost root]# ps -ef | grep mdrecoveryd
root         8     1  0 Apr16 ?        00:00:00 [mdrecoveryd]
root     19558 19411  0 06:03 pts/2    00:00:00 grep mdrecoveryd

[root@localhost root]# ls -alF /proc/8

I've officially reached the end of my knowledge about this. Maybe it will lead 
someone to the answer...
