Automake 1.13.2 failed t/remake-configure-dependencies.sh in two
consecutive attempts on Ubuntu autobuilders. On inspection I found that
our autobuilder network happened to pick the same backend machine each
time, which was a relatively old one still using ext3. (Our newer
builders use ext4.) On running this test in a loop-mounted ext3
filesystem on my laptop, I reproduced the failure first time:

I think perhaps a sprinkling of $sleep is called for in this test?
Thanks,

Thanks for confirming. I'm closing the bug report then, and I'll push
the fix shortly (so that it will appear in Automake 1.13.3, that should
be released this evening or tomorrow).

Stefano
