Comment (by pege):

 `evsignal` in the code above is `1` which would make the signal SIGHUP:

 {{{
 (gdb) print evsignal
 $1 = 1
 }}}

 Looking
 [https://gitweb.torproject.org/tor.git/tree/src/lib/sandbox/sandbox.c?h=tor-0.3.5.8&id=5030edfb534245ed3f7e6b476f38a706247f3cb8#n305
 sandbox.c:305], however, that signal should be allowed.
