[bugs #12044] find still hangs on dead NFS filesystems on Solaris

[James Youngman]

Follow-up Comment #4, bugs #12044 (project findutils):

I tlike the idea of doing stat("..") after the chdir.  I'l have a think about
that to see if it has any hidden gotchas.  



The O_FOLLOW check simply copes with the case where find was compiled on a
new system and is being run on a very old system which ignores the flag.  By
"very old" I mean Linux kernels released prior to Oct 23 1998.   There is no
need to update the check on a yearly basis, because (I hope) support for the
O_NOFOLLOW flag won't be removed. 



Summary: I will have a think about these alternatives and if any are workable
I'll use them.
