Jason seems to have been bitten badly by it. I doubt that fsync() is

below) and worming around its abscence if he wanted TMDA to run on as many
platforms as possible.
This suggests the following questions:
* Is there a reasonable way to write tests which will detect this sort of
* Should there be special documentation about os-dependent functions which
are not universally available? The fsync() doc says nothing about it not
always being available (thus Jason can be forgiven for not calling
