Christophe:
I could be wrong but I would assume that the Performance counter allows more
flexibility then Sleep() does by the simple fact that it doesn't suspend
execution. Am I wrong?

> usleep exists on Win32 as the Sleep command (it takes a
> millisecond value as parameter) so here is the patch for
> making the usleep() php function to work on win32 platforms:
> in main/win95nt.h, line 27: #define php_sleep(t)
> Sleep(t*1000) add the following line so it looks like:
> #define php_sleep(t) Sleep(t*1000) #define usleep(t)
> Sleep(t) and in config.w32.h, line 93: /* Define if you
> have the usleep function. */ #undef HAVE_USLEEP change it
> to: /* Define if you have the usleep function. */ #define
> HAVE_USLEEP 1 -Christophe Thibault Nullsoft
