commit 2994659f1e6c1ef260241491bceca91c9d2553b3 Author: Venkatesh Srinivas <me@endeavour.zapto.org> Date: Sun Mar 6 05:18:24 2011 -0800 kernel -- file desc malloc zone overflow handling. Allow null return from mallocs for file descriptor arrays. Fork and exec will ENOMEM when we cannot allocate FD arrays. This is only a partial solution to bug 2019.
