One thing that would be easy to do is to have an external pool of image
converters that we can call. 
Something like ImageHandler holding 10-20 convert processes alive and
when it is time to convert one image grab a converter from the pool and
tell it to run. That would mean no forking and startup and still mean 
that when a convert process dies the proxy still lives on. 
I do not know of any command line options to convert that can do this, 
but maybe there are other image converters that can. It is also possible
to write a small C/C++ wrapper for convert to handle this.
