Caching should^h^h^h^hshall be transparent to a userland process.
Are you actually advocating that a userland process should
be able to see that zfs is write caching meta data?

The strip(1) command has completed and exited, pola dictates
that anything I asked strip(1) to do be reflected in all commands
or system calls executed after it.

Anything else would be a bug.
