When the build is stalled for some random reason, and mach executed a python subcommand (this may or may not be limited to python 3, I'm not sure, and it doesn't really matter since it's a problem on python 3, which matters most), the subcommand may not have actually sent its last bits of output before the stall because its output is a pipe and in that case python uses buffered outputs. Now, when your build is completely stalled and you ctrl+C, you end up without these bits of output, and in some cases, those bits of output can contain actual information, like... tracebacks. A real life example of this is bug 1624670 when running mach build or mach configure with the patches from bug 1627163 applied, and configure stalls without printing out the ValueError message at all.

==== mach ==== Mach (German for *do*) is a generic command dispatcher for the command line. To use mach, you install the mach core (a Python package), create an executable *driver* script (named whatever you want), and write mach commands. When the *driver* is executed, mach dispatches to the requested command handler automatically. To learn more, read the docs in ``docs/``.
