When trying to activate the Frysk UI, it aborts at startup with the following error:
(No exception message provided)
open: No such file or directory (file /proc/0/stat)
at frysk.sys.proc.Stat.refresh(Stat.cxx:58)

This started happening when I updated from the 2.6.21-1.3228 kernel. Not sure
if there is some significant diff between the 2.6.21 and 2.6.22 kernels or what.

Some debugging reveals:
In LinuxHost ProcChanges.update() is called with pid 2. It thinks it is a new
proc, to get at the parent it does a stat.refresh(2) and then does a
update(stat.ppid) where stat.ppid == 0
Which is correct! process 2 is kthreadd which has ppid 0
This seems to be a new feature of 2.6.22 where kernel threads aren't children of
init (1) according to the kernel, but children of kthreadd.

Fixed by:
2007-07-25 Mark Wielaard <mark@klomp.org>
Fixes bug #4838
* cni/slurp.cxx (uslurp): Catch Errno after tryOpen().
(slurp): Likewise and don't free given buffer and return -1.
(slurp_thread): Likewise.
There is still one issue left with the gui where it throws endless
NullPointerExceptions from the PickProcDialog, but that is unrelated to the
above and seems to be caused by a change in Proc.getExe() that can now return null.
