This is a server issue more than anything else: it happens in times of
server slowness. I got it a couple of times this Sunday afternoon.
In short, splitting way B off from way A requires two writes: one of way B,
then one of the new, shorter way A
If the second write fails, then the points in B will still be in A too.
The solution is either to move splitting ways entirely to the server (so,
although the user hits 'split', the way isn't actually split until the
server returns a message), or to fix the server. I'd be interested to know
_why_ the server runs so slowly at certain times.
I'm not convinced API 0.6 will help: indeed, I suspect it may lead to
increased server load. But others will know more than me.
