[developers] memory issues in [incr tsdb()]

Hi Rebecca -

If you're using a vanilla Lisp image, it may not allow a large enough
heap for what you want to do.  You (or the system administrator if 
you're not running on your own machine) can build a customized Lisp 
image which allows a much larger heap.  See the file 
(which is also pointed to on the DELPH-IN wiki, on the LKBCompilation

Once you've built this image, which will be called "bclim.dxl", you'll 
need to adjust your local settings so you invoke this image when you
start up your Lisp.

If this is too cryptic, maybe you can say more about your current
set-up (operating system, machine, etc.), and we can try to be more
precise about the steps needed.
