Seems solid on 32bit hardy. However, I am getting 26% more memory
allocated than used (with regression.sh, attached):

OrigDataSize:	  221980 kB
ComprDataSize:	  129086 kB
MemUsed:	  163116 kB

XvMalloc got within 12% of ideal in all your tests. I take it ideal is
not the same as zero fragmentation?
