Thanks to Luke Tierney, Agustin Lobo, Stephen Eglen, A.J. Rossini, Simon Wood
and Timothy H. Keitt for responding to my question about poor man's parallel
processing. Much of the substantive material was cc'ed to r-help already, but
my take is as follows.

1) Currently, there is nothing "simple" for solving my problem.

2) I thought that Timothy Keitt's description of the use of a relational
   database for keeping track of different runs was quite interesting.

3) It seems clear that the "future" of this sort of activity lies with RPVM
   (already available on CRAN) and SNOW by Luke Tierney. I found the
   description of SNOW available at
   http://www.stat.umn.edu/~luke/R/cluster/cluster.html to be intriguing. 

4) Since my needs are so simple, I will probably just hack something together
   myself that involves splitting my big.list into 4 chunks in Perl and then
   starting 4 jobs in R from Perl. Once those jobs are complete, I will then
   start an R job that collects the results. At least that is my current
   plan. I plan to follow the progress of RPVM and SNOW closely.

Thanks to all who responded.
