[XeTeX] startup time

[Michael Maxwell]

I've noticed (and you probably have too) that a good proportion--maybe 
half, for a 30 or so page document--of the runtime for a xelatex 
document is startup: reading the style files.  Since I re-use the same 
style files for most papers, I seldom have a mistake in those, so it 
seems a waste to re-run them every time I want a PDF of a new version of 
my doc (or every time xetex finds a mistake in my doc).  Is there no way 
to save the results of loading that, so that it could be re-loaded more 
quickly next time?
