No surprise there as you've not specified the exact option which is whats taking up all
the CPU time. The original post was seeking to obtain exact p-values for the table.
Another alternative to those suggested is the clump routine which was originally written
by Adrian Mander and is based on the stand-alone program clump (see
http://www.mds.qmw.ac.uk/statgen/dcurtis/software.html for source). At present -findit
clump- does not yield any results but if you are interested in the Stata version of clump
then email me and I can forward you the files.
