[REVIEW 3-5]: don't loose data on disk failure (fsync) fdo#40607

[Michael Meeks]

Hi guys,

	I'd love some thoughts on this. Of course, finding the right place to
put the osl_syncFile took a fair while, but then to discover that the
dp_manager was bootstrapping all that UCB-ness just to create and delete
a file, twice on startup each time ... we certainly can't be doing an
fsync on startup on old file-systems it'd be a killer, and just look
like an ultra-slow start.

	Anyhow - hopefully this will save someone some theoretical data, or at
least give a new idea of where to look for data-loss :-) I also tend to
loathe these 'vnd.expand' URLs. I wish we had a simple low-level API for
them we could use everywhere, that had the more complex (?)
configmgr-ness hooked into it at run-time. Anyhow - hopefully this
didn't break some ultra-complicated expansion use-case.

	Thoughts appreciated,

		Michael.
