[R-sig-ME] Bug in lme4a causing disk to become full

[Mike Lawrence]

I've noticed a couple times using lme4a that after a while, my OS
starts to complain that it is low on disk space. Quiting everything
and restarting my computer yields back ~30GB of free space.

The most recent code on which I've had this occur is here:

I'm running Mac OS 10.7.2 on a macbook air with 4GB of RAM. The
phenomena reported above occurs regardless of whether I use R from
Terminal.app or from R.app. Here's my sessionInfo():
