No changes made to these distinfo files.
Otherwise, existing SHA1 digests verified and found to be the same on
the machine holding the existing distfiles (morden). All existing
SHA1 digests retained for now as an audit trail.
Asynchronous programming can be benefitial for performance, however
not all functions are written for nonblocking interaction and
external processes almost never are.
By forking the blocking call into a new process, the main thread may
continue to run non-blocking, while the blocking call evaluates.
Mojo::IOLoop::ForkCall manages the forking and will emit an
event (or execute a callback) when the forked process completes.
Return values are serialized and sent from the child to the parent
via an appropriate pipe for your platform.
