Log Message:
	When the closefrom limit is greater than any of the preserved fds,
	the pfds list will be non-empty but lastfd will be -1 triggering
	an ecalloc(0) assertion.  Instead, test for lastfd being -1 and
	make sure we always update it, even if dup() fails.
	Also restore initial value of lowfd after we are done relocating.
	Fixes bug #633
