On *NIX, one needs to call `waitpid()` in order for process to exit the zombie state. If one uses `Process::isRunning()` to emulate non-blocking wait for child process termination, process will stay zombie and function will always return true. This commit changes `Process::isRunning()` to call `waitpid()` with `WNOHANG` instead of using `kill()` when checking for child process (i.e. the one we have ProcessHandle for), which allows for process termination. Additional trickery with mutex and event is needed to prevent exceptions when `Process::isRunning()` and/or `Process::wait()` is called concurrently on the same handle from different threads. Fixes #1097.

- Focused on solutions to frequently-encountered practical problems.
- Focused on ‘internet-age’ network-centric applications.
- Written in efficient, modern, 100% ANSI/ISO Standard C++.
- Based on and complementing the C++ Standard Library/STL.
- Highly portable and available on many different platforms.

POCO has an active user and contributing community, please visit our web site, forum and blog. Answers to POCO-related questions can also be found on Stack Overflow.
In regards to Boost, in spite of some functional overlapping, POCO is best thought of as a Boost complement (rather than replacement). Side-by-side use of Boost and POCO is a very common occurrence.
