Comment(by mr-4):

 Right, very good news.

 It turns out that the new version of tor + libevent2 (patched) + openvpn +
 my bittorrent client is even more reliable than using the previous version
 of tor with libevent 1.x!

 I have today ran a custom-crafted test script to force tor to serve over
 50 remote dns requests every minute, while resetting openvpn's connection
 (via SIGUSR1) every five minutes, combined with a consistent load of over
 400KiB/s coming through my bittorent client on the vpn end - all this was
 kept going for over 30 minutes.

 Solid as a rock!

 When I used the old system image (with tor 2.2.23 and libevent 1.4) and
 did the same test, it tipped openvpn over the edge after about 15 minutes
 and then the whole thing fell like a pack of cards.

 So, it seems that the patch did a good job and I am well-impressed with
 the performance of the new versions I've got, so that's a bonus!

 Nick, thank you very much for helping out! I am happy that this particular
 bug has been truly squashed.
