Call IO.select with a timeout value and limit the number of retries to

prevent stacking forever.

Subject: [PATCH 2/2] test: use larger keys for SSL tests

Some systems enforce a system-wide policy to restrict key sizes used in

SSL/TLS. Use larger ones if possible so that the test suite runs

successfully.

New PEM files test/openssl/fixtures/pkey/{dh-1,rsa-1,rsa-2,rsa-3}.pem are added

to the tree, and SSL tests now use them instead of the fixed-size keys.
