I suppose you should expect EAGAIN here: http://tinyurl.com/82wr9
describes this situation quite clearly.

So either:
1) ia64 thinks 4120 is less than PIPE_BUF, so that it believes
   that it should not do a partial write
2) Even though we removed some data from the pipe, it thinks that
   it is still all the way full.

[My tests on 2.6.14-rc2].

Which other architectures have you tried this on?  Is ia64 all alone
in failing this test?
