Mitigate long running job for truffleruby in CI by workaround

[supercaracal]

This is just a workaround. I'm not understanding the root cause, sorry. I'd say that it's a pain in the neck because we are made to wait to fail the job with meaningless timeout every time.

I'd rather have it fail than hide the failure.

[supercaracal]

I've simplified it.

It's interesting, it looks like it succeed but then get stuck on exit? Weird.

When I tried the test in my local machine, it was reproduced. It seems that there were three processes for the test and they were waiting for some kind of lock.

Message: <"DENIED Redis is running in protected mode because protected mode is enabled and no password is set for the default user. In this mode connections are only accepted from the loopback interface. If you want to connect from external computers to Redis you may adopt one of the following solutions: 1) Just disable protected mode sending the command 'CONFIG SET protected-mode no' from the loopback interface by connecting to Redis from the same host the server is running, however MAKE SURE Redis is not publicly accessible from internet if you do so. Use CONFIG REWRITE to make this change permanent. 2) Alternatively you can just disable the protected mode by editing the Redis configuration file, and setting the protected mode option to 'no', and then restarting the server. 3) If you started the server manually just for testing, restart it with the '--protected-mode no' option. 4) Set up an authentication password for the default user. NOTE: You only need to do one of the above things in order for the server to start accepting connections from the outside. (redis://10.255.255.254:6381/15)">

I found the following test cases occur the weird behavior in TruffleRuby. https://github.com/redis/redis-rb/blob/6afa62b5a3a89c695158a88420e68d843016b30e/test/redis/ssl_test.rb#L15-L20 https://github.com/redis/redis-rb/blob/6afa62b5a3a89c695158a88420e68d843016b30e/test/redis/ssl_test.rb#L40-L45
