ok, just started tor with this wrapper. Looks like it's working as expected:

anonymizer2:~/tmp# lsof -np `cat /var/run/tor/tor.pid` | grep libhugetlbfs.so
tor     21716 debian-tor  mem       REG                8,1    145282    5390654 /usr/local/lib64/libhugetlbfs.so

anonymizer2:~/tmp# hugeadm --pool-list
      Size  Minimum  Current  Maximum  Default
   2097152      100      107     1000        *

anonymizer2:~/tmp# cat /proc/meminfo | grep -i hugepage
HugePages_Total:     107
HugePages_Free:        0
HugePages_Rsvd:        0
HugePages_Surp:        7
Hugepagesize:       2048 kB

Keep you posted how it changes performance.
Will go to sleep now, Olaf
