 JT> Sounds awesome.  Can you tell us what device?  We always enjoy

http://wiki.mobileread.com/wiki/Hanlin_V3 and
http://wiki.mobileread.com/wiki/N516 -- more to come as part of
http://openinkpot.org/

 JT> To answer part of your question: each shared library has a certain
 JT> overhead, and for a sufficiently short-running program with
 JT> sufficiently many libraries, this overhead becomes noticeable.

 JT> You can overcome some of this cost by prelinking at firmware build
 JT> time, or at install time if you allow upgrades other than full
 JT> firmware flashes.  However, prelinking introduces other fun
 JT> problems.

Yeah, I digged into it.

 JT> Any details on the kind of performance issues you have experienced,
 JT> more specifically?

It could easily take up to 3 seconds on Hanlin V3 just to load shared
libraries for some complex app, such as FBReader (and memory usage
suffers too): http://dumpz.org/17951/
