Another reason to shun halyard locks

[Foolish Muse]

In a boatson.tv interview on What Went Wrong from the Hobart, (you can find it http://www.xssailing.com/
He talks about a problem with locks on the main halyard. They need tension to release. So in a blow, when you are pulling down to reef the main, it will start to climb back up the mast track. I've certainly seen this. But this means that there is no tension on the halyard, so the lock doesn't release, making it impossible to pull the main down again.

I've never liked the idea of halyard locks and this is just another reason.

It should be possible to lock a halyard lock in the open position. I'd have expected this to be standard for offshore.
