TL;DR

Q: Is it better to unlock jobs which after < BTC_JUMP_CONFIRMATION_BLOCKS
A: Yes.

Reason

In the BTCTimeLock contract, MIN_BTC_TIME_LOCK_AFTER=6.

We do this now, and what we need to discuss here is whether to delay processing when the after field of the cell is small then BTC_JUMP_CONFIRMATION_BLOCKS

[Flouse]

When the after field of the cell is smaller then BTC_JUMP_CONFIRMATION_BLOCKS and the related btc transaction confirmation is smaller then BTC_JUMP_CONFIRMATION_BLOCKS, the unlocking btc-time-lock transaction will fail.

So, I think it should be delayed.
