Also look to THREAD sanitize log

A data race occurs when two threads access the same variable concurrently and at least one of the accesses is write. C++11 standard officially bans data races as undefined behavior.{quote}

You have many POOR places in code.

> Valgrind have poor perfomance... slow down 20x+ from native run. 
> Address-sanitizer do only 2x slowdown, but break running after first error found. 
> Becouse our production server have more 100 connected lines we can't test memory leaks.
> In valgrind run we can do only 5-7 connected lines :(
> Now we detect memory leaks using address-sanitizer. 
> I'm provide patch to anyone else who want test with ASAN.
