Completion of error handling

[elfring]

Would you like to add more error handling for return values from functions like “pthread_create”?

The answer would always be "yes". Error testing is always preferred.

This case is very low priority. It's a malloc vs. fio_malloc speed testing snippet. It isn't part of the framework code. I guess I was rushing through it.

I'd be happy to get it fixed (just exit on error), but I prefer to focus on the productive parts.

Thanks!
