Interface LockCorpusOptions

Called once, when the first attempt finds the lock held and waiting begins.

How often a waiting caller tries again (default LOCK_POLL_MS).

Stop waiting: the CorpusLockedError is thrown then.

Injectable for tests; the default sleeps with a timer that signal cuts short.

While another run holds the lock, wait for it instead of throwing CorpusLockedError — what a queue of syncs wants. Checked every pollMs.
