- Add requires_fork and requires_subprocess to more tests - Skip extension import tests if dlopen is not available - Don't assume that _testcapi is a shared extension - Skip a lot of socket tests that don't work on Emscripten - Skip mmap tests, mmap emulation is incomplete - venv does not work yet - Cannot get libc from executable The "entire" test suite is now passing on Emscripten with EMSDK from git head (91 suites are skipped).
