Alas, no go.

| Hi Simon,
|
| Sorry for the rather belated reply; I was knocked off my feet for a few days
| by a rather nasty tetanus vaccination.
|
| Anyways, I have a patch which I suspect will help. It seems that some NFS
| implementations incur a rather long delay (order of seconds) between the
| time a file handle is closed and an open flock lock on the handle being
| released. I suspect this delay won't exist in cases where we explicitly
| funlock before closing the file handle.
|
| I have implemented this in wip/ghc-pkg-locking. Do you think you could give
| this branch a try? If it still fails then we'll have to try to debug things
| in-situ.
|
| Cheers,
|
| - Ben
