implicit non-virtual public destructors.
Was originally:
Replace public nonvirtual destructors in classes with virtual members
with protected nonvirtual destructors where possible, and with
public virtual destructors where destruction of a derived class occurs.
(Excluding chrome/browser/...)
(Part 4 of http://www.gotw.ca/publications/mill18.htm
has a rationale for why public nonvirtual destructors in classes with
virtual members is dangerous.)

Most of these are classes with virtual methods lacking virtual destructors
or NULL used in non-pointer context.

When forking a child process, one often wants to move existing file
descriptors to well known locations (stdout, stderr etc). However,
this is a process bedeviled with corner cases. Consider the case where
you open two file descriptors, get assigned fds 1 and 0 for them and
wish to shuffle them so that they end up in slots 0 and 1. Our current
code fails in this case.
We also have a problem where we're currently trying to mark file
descriptors as close-on-exec rather than closing them in the child
process. This is inherently broken in a multithreaded process where
another thread can open a file descriptor and race the loop which is
trying to mark them.
Thus, on Linux we switch to close-after-fork where we known that no
other threads exist in the process. On Mac, the code is sufficiently
different that this simple fix isn't applicable and one of the Mac
folks will need to take a look.
