Motivation
When forwarding piped output fails after a task process has started—for example, when writing to nonblocking stdout returns
EAGAIN—the runner currently categorizes it as a spawn failure. This produces the misleading messageFailed to spawn processeven though the task did start.This is the remaining lifecycle error described in #506 after #515 separated wait failures.
