Subject: [PATCH] Stop skipping six tests whose reason no longer reproduces

Three skips in test_array say "Hangs", one in test_marshal carries no
reason at all, and two in test_thread say "panic" on Linux. None of the
six does any of that now. Each ran three to five times in a row and
passed, and the array trio was also checked case by case against CPython
3.14, including the mutation-during-index-conversion shapes the tests
were written for.

The neighbouring markers that say "Flaky", "Flakey on CI" and "flaky
EOFError" are left alone. One green run says nothing about those.
