Hi Sergey, Thanks for the review. I would push the fix into 5.5 if there are no buildbot failures. There seems to be something wrong with solaris though. Need to #ifdef the __sync_synchronize() there. The patch generally applies to 5.5 as well. Since we're having a 5.5 week next, I'll test it for 5.5 as well, then push.

Hi Vicentiu,

Ok to push. This patch is against 10.2, do you plan to fix previous versions separately?
