It seems https://github.com/php/php-src/commit/eb951b3d11109aa16982a2132f8d1fd5129edc9e
already tried to fix this by increasing the sleep from 10ms to 20ms for slow ASAN jobs. While
working on CI and test batching I ran into it again with
ALPINE_X64_ASAN_DEBUG_ZTS.
The server assumed one delayed fread() is one MySQL request, which TCP does not
guarantee. Now reads complete packets, including partials.
### Test Failure
