Ok, that could be a lot of things happening . To
reduce
memory footprint, you can switch to the slower engine
flavours (the more you JIT, the more memory it takes) 
like the direct threaded or token threaded engine .
Try disabling IL_CONFIG_UNROLL in include/il_profile.h
should save at least half of that space for an 
equivalent hit in speed :)

Also, I hope mmap is working for you properly :)

Since you're doing it for embedded systems, I assume
you've read
(http://www.southern-storm.com.au/doc/embedded.html)
?.

The Latin1 option and Reduce Code can help a lot
if you have to put it on flash. (btw, I was playing
around with pnet on top of OSE Delta, didn't make it).
