Hi guys,

This is just plain odd. I thought it was something I was doing wrong,
but now several people I have shown also agree this is strange (you
guys are all CC'd in).

$ sudo /sbin/ifconfig ral0 nwid b0rk
$ sudo /sbin/ifconfig ral0
ral0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        lladdr 00:12:0e:61:5b:74
        groups: wlan egress
        media: IEEE802.11 autoselect
        status: no network
        ieee80211: nwid b0rk 100dBm
        inet6 fe80::212:eff:fe61:5b74%ral0 prefixlen 64 scopeid 0x2
        inet 192.168.84.91 netmask 0xffffff00 broadcast 192.168.84.255

Now we are in a state where the wireless network can't work, there is
no such network as 'b0rk'

Now xterms will not run. BUT... If I switch from xfce to cwm, I do not
observe this behavior.

Here is a ktrace:
 19446 ktrace   RET   ktrace 0
 19446 ktrace   CALL  execve(0xcfbec0c0,0xcfbec618,0xcfbec620)
 19446 ktrace   NAMI  "/bin/xterm"
 19446 ktrace   RET   execve -1 errno 2 No such file or directory
 19446 ktrace   CALL  execve(0xcfbec0c0,0xcfbec618,0xcfbec620)
 19446 ktrace   NAMI  "/usr/bin/xterm"
 19446 ktrace   RET   execve -1 errno 2 No such file or directory
 19446 ktrace   CALL  execve(0xcfbec0c0,0xcfbec618,0xcfbec620)
 19446 ktrace   NAMI  "/usr/local/bin/xterm"
 19446 ktrace   RET   execve -1 errno 2 No such file or directory
 19446 ktrace   CALL  execve(0xcfbec0c0,0xcfbec618,0xcfbec620)
 19446 ktrace   NAMI  "/usr/X11R6/bin/xterm"

What we see here is the shell (ksh) looking for the xterm binary,
finding it, but never executing it.

Oga@ suggested I build a debug libc and get a backtrace. Here this is:
(gdb) bt

If I then fix/take down the network interface, within 10 seconds the
process will unblock and the xterms will appear.

Further, if you start xfce in an inconsistent state, it wont start. As
soon as you fix or take down the wifi, it starts.

I used to think this only happened on ral, but come to think of it my
wi did this too.
My question is why is this happening?
