gjournal: FLUSHCACHE timed out

[Andriy Gapon]

It seems that setting switch_time to 5 helped only against small loads
and I still saw timeouts in some cases.

Unfortunately I lost Pavel's reply but I saw it in the web archives and
I applied the patch from:
http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/ata/ata-disk.c.diff?r1=1.201;r2=1.202
and everything is perfect now!

I set switch_time back to 10 and I don't see any timeouts even under
heavy loads.
Thank you, Pavel!

Also, according to the given advices I disabled softupdates and set
async mount option.

Thank you all again.
