Comment (by jdgleeson@…):

 Since I have a case where this problem is reproducible, I'm trying to
 think of ways to help debug it. I came across the iosnoop script, which I
 thought could make it clear what system I/O operations cause the data
 loss. I've tried many variations on
 {{{
 sudo iosnoop -av -f `port logfile atlas`
 }}}
 but I get no trace output.

 I'd welcome any debugging ideas.

 NB: It takes 12 hours for this atlas install to run, so it is a rather
 inconvenient reproducible case. I don't know how much I can perturb it and
 still see the log file bug. I've tried a trivial "port -f uninstall
 atlas...; port -k upgrade atlas" without an intermediate clean, but the
 resulting log file was complete. I'm now looking into making and using my
 own architectural defaults, which I hope will reduce the build time to
 about 30 min.  Any other ideas would be welcome (for purposes of
 debugging, I don't care if they  give poor atlas libraries).
