This will become a non-issue when the prctl() calls are moved into the
fr_suid_* functions. :)
Would you like me to prepare a patch for that or would you rather do
that yourself?

Anyway, here's the aftermath: I got my core dump, finally, and it turns
out that we are probably hit by the notorious bug #35 (as I half feared,
half hoped :).
I will try the fix for list_delete() you proposed if I can get to it...
