untarring symlinks with ../ fails randomly, silghtly OT

[Wolf Geldmacher]

As an aside:
	I also used to have some trouble with "rm -rf" of a directory
	hierarchy failing more or less reproducibly (like: 80% of the
	time) because files were presumably still "in use". Repeating
	the command several times would succeed, though.

	Downgrading from cygwin1.dll/1.7.9.1 to cygwin1.dll/1.7.8.1
	seems to have solved that issue as well - still have to see
	the first "retry to delete".

This may or may not be related to the original report, as it also reeks
of a race condition during file/directory operations.

Cheers,
Wolf
