Milage may vary.  I keyed in my results by hand so that I could format
them into a table.  I hope there are no typos.  Also, don't be surprised
if overall all the results appear "slow," this machine is a little
"slow" itself.

Currently, with only m_free() mod == euclid1
With the m_freem() modification == euclid2
