Windows: fix all failing tests.

This makes the testsuite pass clean on Windows again.
It also fixes the `libstdc++-6.dll` error harbormaster
was showing.

I'm marking some tests as isolated tests to reduce their
flakiness (mostly concurrency tests) when the test system
is under heavy load.

Updates process submodule.

Test Plan: ./validate
