First, why would you want to disable retrying a request? This only
happens when you've told curl that it's okay to re-use connections. To
be in this code, you tried to re-use a connection but failed. Are you
saying that you want your code to always use a new connection, or to
give up entirely if it cannot re-use a connection?

Second, there's already a way to disable connection re-use. The third
line of this conditional, "conn->bits.reuse" checks whether re-use is
enabled or not. You can already configure this with CURLOPT_FORBID_REUSE.

What problem are you trying to solve, exactly?
