No numbers or comparisons yet, we were finishing the Canola release
until yesterday, so no time for that, but I'd appreciate if someone
does that :-)

While coding, I tried to be light on resources, avoid memory
allocation, avoid walking strings all the time, etc...  The only point
of slowness is the dual-process approach, since you have lots of
context switches, but it's the price of it not breaking your main
process with bogus libraries.

Also, some plugins could be profiled and improved. For example, the
JPEG/EXIF plugin was written from scratch to make it lighter, but I'm
now doing lots of lseek() and read(), maybe profiling can show that
it's cheaper to mmap() the file and set a good posix_fadvise(), but
since we're working with flash memory and not disk, then it should not
import that much... and the kernel does some caching for us.
