     Hi Olaf!  That looks like a renewed call for someone to either a) adapt
the OpenBSD version of malloc()/free() shipped with tor to be compatible with
the libhugetlbfs runtime library for LINUX or b) find and fix the memory leak
in the native LINUX malloc()/free() routines.  One or the other appears to be
required, given the lack of up-to-date VM support for Intel x86 hardware in
the LINUX kernel. ;-)  The alternative, of course, would be to switch to an
OS whose kernel does have up-to-date support.

     Very impressive, as usual!  Many thanks again for your ongoing
contribution to the tor relay network's overall capacity!
