Hash table management was a part of my computer science core curriculum;
it isn't _that_ hard.

Also, for C programmers, there's standard library hash management
functions that are easy to use (never try to re-invent the wheel!).  See
"man hcreate_r" (although it is unfortunately just a GNU extension to
have multiple hash tables).

Now, given that, I still write most of my system admin stuff in perl.

I don't speak for anybody but myself - that's enough trouble.
