           Summary: 9p: Frequent bad file descriptors from u9fs

 So ever since I actually converted to u9fs on my server, I keep getting:
ls: cannot access /home/sqweek/mail//new: Bad file descriptor
 I have a precmd that checks my maildir every time a prompt is
displayed, and every time it hits problems it seems to be just as I
open a new terminal (and therefore shell, of course) - often enough
because I just got a mail notification so I open a new terminal to
check it.
 Here's what the serverside u9fs log has to say:

<- Twalk tag 0 fid 10 newfid 11 nwname 0
-> Rwalk tag 0 nwqid 0
<- Topen tag 0 fid 11 mode 0
-> Ropen tag 0 qid (0000000000058211 1193059597 d) iounit 0
<- Twalk tag 0 fid 10 newfid 12 nwname 0
-> Rwalk tag 0 nwqid 0
<- Tstat tag 0 fid 12
-> Rstat tag 0  stat 'new' 'sqweek' 'wheel' '' q (0000000000058211
1193059597 d) m 020000000755 at 1193066604 mt 1193059597 l 0 t 0 d 0
<- Tclunk tag 0 fid 12
-> Rclunk tag 0
<- Tread tag 0 fid 11 offset 0 count 8192
-> Rread tag 0 count 0 ''
<- Tclunk tag 0 fid 11
-> Rclunk tag 0
<- Twalk tag 0 fid 9 newfid 11 nwname 0
-> Rwalk tag 0 nwqid 0
<- Tflush tag 1 oldtag 0
-> Rflush tag 1
<- Twalk tag 0 fid 9 newfid 11 nwname 0
-> Rerror tag 0 ename fid already in use
<- Twalk tag 0 fid 10 newfid 11 nwname 0
-> Rerror tag 0 ename fid already in use

 It does appear that fid 11 is attempting to be reused without being
clunked, but I'm *far* from fluent with 9p, so I post it to an
audience that is.
