Currently programs with -race fail with:
==1815==ThreadSanitizer: Thread limit (8192 threads) exceeded. Dying.


There is a limit on amount of simultaneously alive goroutines.
We need to print a more informative message, add a link to a web page saying what to do
in this case.
Probably remove "ThreadSanitizer" since the race detector is not branded as
ThreadSanitizer.
Look into increasing this limit to say 16K.
