If command line option '-p' is provided, start/fork all tests in the
main thread and then gather them in order at the end. On a laptop test
time was reduced from 5 minutes 21 seconds to 1 minute 50 seconds. The
option isn't default as the test shows up perf and test flakes.
The '-v' option is modified so that 'perf test -v' will give verbose
output only from failing tests.
v3 - fix a crash if shell test directory isn't found, remove merged patch.
v2 - fix parallel test output/verbose issue
v1 - initial PoC
