Answered my own question over a donut run.... (left them running while
I went out, and discovered them working fine when I returned.)

On a heavily loaded system this routine takes forever to load!!!!

On our webserver (a 3000/600 w 512meg) and a moderately heavy I/O load
it takes about 10 minutes to initialize.

On our news server (a 2100 with 512meg) and a very heavy I/O load it takes
almost 15 minutes to initialize!

Once initialized it runs (apparently) as expected.
