FUD. Tried it for myself. Withdrawl from gox took less then a minute.
A few days ago I had a 100 BTC withdrawal from Gox delayed by about 40 hours.
I currently have 3 BTC withdrawals in GoxLimbo at the moment, 100, 51 and 49 BTC.
Not that I am particularly bothered by delays as I am in the tedious process of moving all my BTC off Gox to keep in my own cold storage, but it doesn't inspire much confidence.
I actually always break up my moves into smaller chunks. Dunno if that would have helped.
