[plt-scheme] drscheme syntax coloring in normal editing?

My motivation isn't Scheme but ML and Java, so I'm most certainly going 
for emacs-mode functionality and not check syntax functionality.  My 
basic idea is to lex the buffer and incrementally update the tokens.  
This will never be wrong, but the cost of inserting/deleting a string 
or block comment delimiter could be very high.  I think a separate 
thread would be the best solution, but I'm not sure how to implement 
that in a safe way for the text%.  If that fails then limiting the work 
to the next few/previous lines should be a workable solution.

BTW, this project is made possible by the new editor modes.
