[R] loading .RData on distributed system

I'm running R on a beowulf system, with software that can take a list of
single-processor jobs and parcel them out over the system. (In case it's
of interest, they're dual pentium 866 machines connected by fast
ethernet.) The administrators of the system found that I was causing a
huge load on the file server, and when they investigated it turned out
that each process was reading in .RData 4 bytes at a time. Not kilobytes,
bytes. The .RData in question is several megabytes, and more than one
process is starting up at a time, so apparently it really adds up.
I looked through the documentation, and a little bit in some of the
source, and haven't been able to find how exactly .RData is read. Is this
part of the program? Is it something I can set? Is it something strange
happening with the file system on the beowulf cluster?
Any help appreciated.
