Yes.  There's no time limit at present, but it will be easy to add one
after we change to fork-before-authenticate (since each PM child can
have its own itimer).

Unfortunately I only have Stevens' first edition, and it doesn't seem
to have any such advice in it.  Why is it a good idea to ignore the
