I tested this patch, and it appears to fix the overflow problem.

(FWIW, I tested using https://gist.github.com/rprichard/bcff3b3fb0451207dc9f31ccbab938df on Wine and on Windows 10. For both targets, the performance counter frequency was 10MHz, so `counter.QuadPart * nano::den` had previously wrapped around about every 1845 seconds.)
