Hanging in Rails Console

[mlh758]

When I run a Rails console and access a new model (triggers a describe) there's a high chance that the operation will lock up the console. My CPU usage shoots up like it's stuck in a tight loop somewhere.

Here is a stack trace and sample output from the process during a freeze.

This only happens in development with a Rails console. If I run a Rails server or run ActiveJob I'm not getting any problems. I tried upgrading versions of instant client and that also did not help. I imagine this isn't impacting a lot of people but I can reproduce this reliably.

I also opened an issue with Oracle Enhanced but after looking at the stack traces it seems to happen in oci8_do_describe which means it might be more with this repo than theirs.
