After investigating the issue some more, it appears that this is impossible
without a C extension.

The ossl_start_ssl() function in ossl_ssl.c, which is used by both
OpenSSL::SSL::SSLSocket#connect and #accept, contains a loop which calls
SSL_connect() or SSL_accept() repeatedly.  If either of these functions
needs the socket to be in a readable or writable state,
rb_io_wait_readable() or rb_io_wait_writable() is called, blocking the
application.

Has there been any consideration as to adding something like
OpenSSL::SSL::SSLSocket#connect_nonblock and #accept_nonblock to go along
with Socket#connect_nonblock and Socket#accept_nonblock?
