While this seemed to have been working okay, it's started failing again consistently. The pattern is that Xcode will save the file once, but after that you get errors each time you try to save. I have found that alternately creating or removing (if it exists or doesn't) the directory:
$HOME/Library/Caches/TemporaryItems/(A Document Being Saved By Xcode)
means that the save will (usually) work.
My suspicion here is that Xcode is using something like chflags(2) on the file/directory as a way of locking it. That works on HFS+ and other file systems but fails on NFS (returns ENOTSUP).
I've logged a bug with Apple but, well, my experience with seeing these sort of bugs fixed has not been confidence inspiring.
Does anyone have any other suggestions about how to deal with this? Is there an option somewhere to ask Xcode not to use its fancy save strategy?
I'm using Xcode 3.2.6 on Mac OS X 10.6.7.
