Like bug 1435376, we should attempt to determine if the profile is on a networked drive and set NSS_SDB_USE_CACHE accordingly. I'm hoping the same APIs can be used for linux/OS X but I'm not really holding my breath. We can separate the two platforms if that doesn't work.

The solution I found for linux won't directly work on OS X (but it does look very similar).

Comment on attachment 8958612 [details] bug 1444943 - set NSS_SDB_USE_CACHE to yes if the profile is on an nfs mount https://reviewboard.mozilla.org/r/227522/#review233352 `NFS_SUPER_MAGIC` is a blast from the past. Geez. Anyway, LGTM, should work fine as-is. It will get somewhat uglier with OSX and FreeBSD added to the mix. I recommend that when we add another platform we do so by adding something into a util. Heaven forbid, but maybe even an NSPR method `is_path_on_nfs`?

Try looks good: https://treeherder.mozilla.org/#/jobs?repo=try&revision=7fb02c9bd31d0095edaec6012ae89479072d99ae Thanks for the reviews!
