You do know that Firefox had to _disable_ fsync() exactly because not 
disabling it was unacceptable? That whole "why does firefox stop for 5 
seconds" thing created too many bug-reports.

No they don't. Read up on it. Really.

Guys, I don't understand why you even argue. I've been complaining about 
fsync() performance for the last five years or so. It's taken you a long 
time to finally realize, and you still don't seem to "get it".

PEOPLE LITERALLY REMOVE 'fsync()' CALLS BECAUSE THEY ARE UNACCEPTABLE FOR 
USERS.

It really is that simple.
