Comment:

 I tested building zlib with buildmakejobs=2 several times. Usually it
 succeeded, but sometimes it didn't. I did not see the specific error
 reported above, but I did see these failures which look similar:

 {{{

 I disabled the parallel build in r66834 and reported the problem to the
 developers of zlib.
