public ssize_t propagate_int () throws Error
Gets the result of this as an integer (ssize_t).
If the task resulted in an error, or was cancelled, then this will instead return -1 and set throws.
Since this method transfers ownership of the return value (or error) to the caller, you may only call it once.
