------------------------------+-----------------------------------------
This happens on a fully updated Slackware64-14.2 system with tor 0.3.2.9
after an update to kernel 4.4.118 that fixes Spectre variant 1. Same
version of tor worked fine with a few previous 4.4.x kernel versions
(4.4.115, 4.4.111, 4.4.88). Tor process freezes in uninterruptible state
as soon as a program anonymized using this guideline

tries to get online. Symptoms are similar to the ones described in this
ticket https://trac.torproject.org/projects/tor/ticket/25380

reproduce the issue independently can be found in this forum thread
