I use the master version of org, and some months ago the time required
to generate my custom agenda view sky rocketed.  I've found that 90% of
the time was being spent in the call to re-search-forward in
org-refresh-category-properties.  The patch below speeds up the regular
expression search and makes the generation of my agenda as fast as
before.
