Ouch...of course I meant "-Xmx1024M".  Sigh...

Yes, that's true.  Unfortunately, in order to compile my largest document, 
even 512 was not enough.  Because I actually render fairly infrequently 
(several times a week at most), the performance degradation doesn't affect 
me all that much.  I should have observed to Susan that my situation might 
be different from hers and that she should try 256 or 512.

Thanks for letting me clarify!
