While this may be useful for those doing testing, I'm wondering if such a
sysctl should be implemented.  I have this bad feeling about
net.inet.tcp.tcprexmtthresh=1 being added to the bogus pile of sysctls
that should be changed which is sent to every person who asks how to tune
their system.  (Just look back through mailing list archives to see how
man tweaks people are making that shouldn't be made.)
