     That does look promising, then.  Perhaps Olaf and others can use that
method for now.

     Thanks much for these URLs, Arjan.  I've started going through this
thread, but it's a horrendous lot to digest and full of LINUXisms that
I know nothing about.  I have some errands to run, and then I really *must*
get some sleep.  Maybe late tonight I'll continue reading.
     In the meantime, perhaps some adventurous relay operator using LINUX
could begin experimenting with the libhugetlbfs-in-LD_PRELOAD method to
see whether tor functions okay with it and then report the results back
to the list.  I'll be offline for at least 10 - 12 hours.  Best of luck!
