I think we should assert that available is never negative and make sure that
available throws an exception if -1 is returned from the system call. We have it
on our OKRs to go through the error handling in the IO subsystem.

Removed this check here and added an asserion in the native code for available
being always >= 0.
When you do your cleanup you can take care of this.
