-          but has two comments nonetheless:
-          a) with no abort function specified for the pools, this is just
-             one of many possible failures
-          b) my guess is that a heap shortage encountered by ab is
-             much more likely to be caused by an ab bug instead of by a
-             user setup error (ulimit) or system resource shortage...
-             is an error message better than a coredump in that case?
-
-          nd: hmm. This one is a pure (and obvious) malloc. Once we may
-              decide to use a pool-abort_fn; then the situation turns
-              around... :)
-              Yes, I think, a useful error message is better than
-              a coredump in this case.
