What's wrong:
/afs/athena/user/e/eichin/mbox is a protected directory (it only has
"rlidwka" access for "eichin", and noone else.) I was grepping through
it and did an attach, and seem to have scrambled my tokens...
portnoy% grep -i clock ~/mbox/*

Note here that I *could* "fs la mbox", but not read or cd into it; it
seems inconsistent at best.
{{{{ note: doing an "aklog" restored the access. I couldn't duplicate
it right away; however, *every* time I log in (at least on the RT) I
get messages like
./athena/orom/stringtab.el: Permission denied
./elisp/discuss-ls.el: Permission denied
./bin/Binrt/block: Permission denied
from a "du" I run in parallel with my attaches - though note that none
of the files listed here are actually protected, so it's not exactly
the same symptom as the mbox problem above.}}}
What should have happened:
None of the above... I should never have lost it in the first place,
but likewise I shouldn't have lost *part* of my access.
