Would be good to have an pre-build wheel of the uvloop python package for musl & glib on armv7. https://github.com/MagicStack/uvloop/blob/7bb12a174884b2ec8b3162a08564e5fb8a5c6b39/.github/workflows/release.yml#L86 There are still some scenarios for this, e.g. the millions...

SSLWantReadError is expensive. https://github.com/python/cpython/issues/123954 This PR tries to predict that there will be SSLWantReadError by checking incoming.pending and SSLObject.pending() first. This check works in 99% of cases. For the rest...

After profiling my app with perf I identified a couple of things that make SSLProtocol a little bit faster: * SSLProtocol.get_buffer and buffer_updated can be called directly from UVStream since...
Use `shlex.split()` to split the flags in `UVLOOP_OPT_FLAGS`, permitting the user to pass any number of flags rather than exactly one. This can be used e.g. to pass `-O2 -flto`.
