What's wrong:
For the purposes of this example, you should know that "tktsw" is my
alias to switch between ticket files. "tktme" always returns me to my
login tickets. At the start of this example, I've initialized the
hillel tickets already.

w20-575-52% attach hillel
hillel: NFS mounted HERA.MIT.EDU:/mit/lockers/hillel on /mit/hillel (read-write)

What should have happened:
As far as I can see, there are two bugs here... First of all, it let
me create a file in the hillel directory (which is mode 711, by the
way), but once it let me create it it wouldn't let me modify it (i.e.
touch it again). Then, after I supposedly unmapped with hera, I was
still able to remove and touch the file, even though I shouldn't have
had a mapping. It took a full purge in order to really get rid of the
mapping between jik on w20-575-52 and hillel on hera.
