Well, (In reply to John Marino from comment #1)

Hi, John! Well, I'm not an expert here.
I mean I know what's mmap(), dirty page or flush, but I'm not a developer to
argue whether we need this patch.

Hi, emz@!

I see you wrote 'regression'. Could you, please, explain a bit.
What do you call regression and why? What if squid should work as it does now?
If I don't use cache I'm not affected?

Did you try to write about this change to the official squid maillist or create
a PR in their bugzilla? Or it's too FreeBSD specific? I could do it if you
don't have time. I could ask and see what happens.

As I see, squid-3.5 now has the same mmap() call, without MAP_NOSYNC.
