questions that can really derail a sunday evening:
is std::cout thread-safe?
(not in the way you'd want it to be, no)
Consider this code. One thread repeatedly prints the number 100 in decimal to std::cout. Another thread repeatedly prints the number 0x100 in hex (which will output as '100') to std::cout.
You might reasonably expect that the output will simply be '100' over and over and over.
Unfortunately, the calls to operator<< can get interleaved so you end up with crosstalk of the format specifiers:
@luna The whole modal formatting thing is gratuitously stupid. It's slower, uglier, and had awful gotchas like this compared to printf.
