R help - May 2004 - Stopping the process after a certain time

Greetings R-community,

I'm running simulations within R that I wrote in C.  The simulations
require fitting that occasionally fails to finish.  I was wondering if
there is any kind of tool for process control in R, such that after e.g.
15 minutes I could kill the process, record the state for post-hoc
analysis, and move to the next simulation?

I'm running FreeBSD and could almost surely do something in Perl but I'd
rather stay inside R if possible.

Thanks,

Andrew

As one component of this, if you send an R process SIGUSR1 it will quit
and save .RData (approximately the equivalent of CTRL-C, q("yes")).
