That way if the remote service doesn't respond at all for some
reason users can have fine control. That's a sufficiently targetted
use case that it'd be easy to do, compared to timeouts for arbitrary
APIs.
Indeed - having a timeout on the initial connection attempt is much more
useful than worrying about individual APIs when you have a responsive
connection, since it is the indeterminate time of establishing a remote
connection that may be the problem here. But does that mean yet another
C API? We already have virConnectOpen{,ReadOnly,Auth}. Or are you
envisioning this just in the language bindings (Java, python - but not C)?
