Huh? If ulimit causes a failure, one can always create or extend
another file, so long as that file is smaller than the ulimit. It is
quotas that would screw you there. And if you want to test for write
failure on the additional file, that too can be arranged simply
enough.

Don't be silly. All test environments are deficient in some way or
another. It's called cost. And practicality. It is wholly useless to
argue that one should have extra hardware to test an error condition
when it is entirely possible and extremely easy to simulate the error
condition using software.

Tell me, does your testing environment include hardware that you can
do things to like smoking chips to see if the OS will recover from the
induced parity errors? How about an alpha-hit generator? A disk that
is partly defective? An OS that crashes randomly? A user that enjoys
destroying keyboards while your program is running?

I thought not.

Why did you make such an irrelevant, and nasty, statement?
