- There may be a libc stdio function which allows you to tune this
behaviour.
- libc should probably be a bit more defensive about this anyway -
plainly the filesystem is being silly.
I really thank you for isolating the problem, but I don't see how you
can do other than blame glibc for this. The recommended IO size is only
relevant to uncached data, and glibc is using it regardless of whether
or not it is cached or uncached. Do I misunderstand something myself here?
I think the issue is not "blame" but what effect this behavior would
have on things like database loads, where seek-write would be common.
Good to get this info to users and admins.
