Details:

I'm compiling OpenWRT in parallel. However if I add a compile error to a
package and use the output-sync option, there is a ton of output missing. With
unbuffered output, there are six times as many lines in the output as with
--output-sync, and the output is four times the size. So with --output-sync
there is a ton of output missing, including the error message, and the entire
package it's in.
