Hi Maxim,

For this patch to cover TEST 3 in my previously attached test suite
(cancel binary upgrade via SIGQUIT on the new binary), we need a way for
a new binary to know whether an old binary is still running or not.

Do you have another suggestion on how to achieve this? Checking for the
existence of nginx.oldpid seems acceptable to me in this case.
