JDK-8077350 - JEP 102 Process API Updates Implementation
Description
The implementation of ProcessHandle.isAlive should be more robust
and handle OS failure to return the process status.
The current implementation on Linux uses kill(0);  If the OS denies access to kill
the implementation may incorrectly report the process is alive.
Additional measures like reading /proc/pid should be added.
