I've looked a bit now, and two of the leftover NFS files I could find
were configure and install-sh.

These failures are not new, see this older report:
http://thread.gmane.org/gmane.comp.sysutils.automake.patches/5038/focus=5092
The failures seem to happen only on some Solaris systems, more
specifically only on i386-pc-solaris2.10 and sparc-sun-solaris2.10.
The failures are 100% reliable AFAICS (i.e., happen every time).

A git bisect shows that the failures already happen with Automake 1.9.6,
so at least there seems to be no recent Automake regression.  Notably I
cannot find failure instances in my historic testsuite logs from 1.9a
in 2006 on this particular host however, and aclocal13.test passed as
late as 2009-04-19 in Automake 1.10c.  I did not try older Autoconf
or M4 versions yet, however.

Running lsof on the $(distdir) directory recursively right before the
final `rm -rf "$(distdir)"' does not show any processes holding files
open.

I suspect a Solaris NFS implementation update regression or a hardware
bug.  The fact that Dave saw similar issues makes the former more
likely.

If anyone has further data, please add them here.  Who can report this
upstream?

Thanks,
Ralf

According to the details in the report, this issue was probably due
to a bug on Solaris NFS support.  Also, this bug hasn't seen any
activity in the past three years, and it's extremely unlikely it
will see any in the foreseeable future.  I'm thus closing it to
reduce the clutter in our bug tracker.

If anyone can reproduce this issue *and* has ideas for a fix can
feel free to reopen it.

Regard,
  Stefano
