Arg --processtimeout does not kill running tests

[jkeset]

Issue:
There is a related issue #321 that got fixed by introducing --processtimeout. The problem is however, when a person running rfbrowser tests in parallel tries to use it, it will end the process in the terminal display BUT the actual test execution keeps going, you can see the browsers are still running and executing keywords. This can cause a big resource bloat since 'timed out' tests will be executed alongside newly open browsers in freed threads.

EDIT: This also causes the log file from given process to be 'in use' preventing further data processing.

Expected behaviour?:
When a process 'times out' it should kill the test execution.

cmd input:
pabot --testlevelsplit --processes 2 --processtimeout 10 samplerobotfile.robot
