I'd hate to lose the ability to disable fsync.  I run tons of tests that
don't require any protection against server crashes or hardware failures,
but their speed does matter.  I know it's not the most important
requirement in the world, but speeding up those tests means I can run more
of them, on more hardware, more often.  Test time also affects my
development cycle.

My main worry is where the option is set, though.  For my situation,
selecting a "fast and sloppy" mode when starting the server is clearly the
best choice.  It'd be possible, though awkward, to change my code to use
COMMIT NOWAIT.  But then am I really sure I'm still testing the same
thing?  Plus it introduces a risk of binaries (distributed by others)
accidentally doing COMMIT NOWAIT, as for testing, in production code.
