Bug [336441ed59]: Buffer infoPtr between socket creation and insertion into info structure in thread local memory. Backported fix from commit [65b320b464] from branch "bug-[13d3af3ad5]".
Be shure tsd pointer to the info structure is invalidated before memory free
Set all variables written by the notifier thread as volatile.
Test to demonstrate bug [336441ed59]. Depends on timing and will not always fire but is better than nothing. Reliable for me.
