Re: [PATCH] "sleep 1" sleeps too little on cygwin

[Junio C Hamano <junkio@cox.net>]

Sorry, but the previous patch turns out to be bogus as well.
'touch' did not affect the timestamp of the symbolic link but
ended up creating a file pointed by it, and since we (hopefully)
correctly do lstat() not stat(), it did not have any good
effect.  Here is an replacement.

Subject: [PATCH] t4011: "sleep 1" sleeps too little on cygwin

This test depended on "sleep 1" not to return until the next
second boundary, to get a dirty index entry.  An initial fix was
provided by Alex Riesen using a bashism $SECONDS, but make it a
bit more portable, and also work around a potential problem on a
filesystem with coarser-than-a-second timestamp granularity,
this patch fixes it a bit differently.

The test is checking if we correctly notice the stat changes,
and the timestamp is not the only thing we have in the stat part
of the index.  This commit fixes the problem by leaving the
original symlink we create on the filesystem, so that it keeps
the inode number used for the original symlink in use, and then
create a second one which should get a different inode number.
