>Description:
	Child processes of portupgrade-devel-2.3.0_5 appear to have
	many open file descriptors (>50 in some cases) apprently
	inherited from portupgrade.

	Portupgrade should probably either set the close on exec
	(FD_CLOEXEC) flag when opening files like +CONTENT, or
	explicitly close all non-essential file descriptors after
	fork and before exec.

>How-To-Repeat:
	Upgrade a port with many dependencies.  While it's running,
	run 'fstat' in another window.  Observe the unnaturally
	large number of open file descriptors for processes like
	'make' and 'sh'.
