This is more of a theoretical question.
When I run a PHP script that does a passthru to some other program, say a Java application, let's assume that program works for 30 minutes and then ends gracefully and PHP keeps calling it in a loop every single time...
... does the time PHP stays idle waiting for Java count as execution time or as idle time?
This manual page seems to indicate that on Windows the time will count as execution time, whereas on Linux it will not.
