No, there's no specific need for it to be 2000 - it may as well be 300.
I just wanted to stay on the safe side, but I think 300 should be still
more than enough time for PLL to lock.

Yes, V1 breaks more things than it fixes, so it would be nice if
it can be replaced with fixed version (I hope it's not too late yet).
BTW, regarding timeout discussion above - should I resend patch with
adjusted timeout, or can you change it while applying? (of course,
if we settle on incremental patch, I'll roll this change in)
