I did not see anyway that a java program could find out if the
required syncing was being enforced.
Would it be reasonable to request such an API call in some future java
version or would it just simply be impossible to implement?
Actually there already is, the FileDescriptor.sync() call has this in
its defined contract:
SyncFailedException - Thrown when the buffers cannot be flushed, or
because the system cannot guarantee that all the buffers have been
synchronized with physical media.
The problem maybe that the JVMs just do not implement this according to
the spec. It also maybe true that a VM has no way of knowing if it could
guarantee a sync, thus in reality it would throw SyncFailedException all
the time ...
