Provide an argument to wait before resuming after an error

If something wrong happens, I might want to take a look before the process is continued, perhaps I'd not like to continue ?

Possibly with a timeout, and based on the severity of the error ( fatal, warning, info, etc )

The issue names no files, tests, or entry points. First inspect the import error-handling flow and clarify whether pausing, timeouts, and severity-specific behavior are required; done means the behavior is agreed, implemented, and covered by tests.
