Hmm. From man mount on FreeBSD 4:
async All I/O to the file system should be done asynchronously.
This is a dangerous flag to set, and should not be used
unless you are prepared to recreate the file system
should your system crash.
noasync
Metadata I/O should be done synchronously, while data I/O
should be done asynchronously. This is the default.
sync All I/O to the file system should be done synchronously.
