This is a regression of commit 4db0017, using stream_socket_recvfrom()
bypasses stream wrappers thus read/write timeouts handled by PHP. The
only way to make them work again is to fetch the raw socket from the
stream resource and use socket_import_stream() which is unfortunately
a PHP 5.4+ function.
Casting values supplied by users should be done by the consumer since
we cannot cover any possible use case anyway. It is still possible to
subclass Predis\Connection\Parameters and override the filter() method
to convert certain values if deemed necessary.
