This change introduces a new command-line parameter to enable
parallel execution by a specified number of worker threads. When
parallel execution is requested, tests are distributed across
the worker threads. This behaviour is disabled by default.
This does not currently work for all suites as some of them are
using global variables to configure tests. For the suites that
do not use global state, this change reduced the execution time
by up to 5x on an 8-core machine.
