------------------------


A problem often encountered with massive parallel
builds is that the qmake output is hardly usable.
The outputs of simultaneous builds are being
mangled and it is very difficult to find out which
warnings/errors come from which compilation.

The problem is  not qmake specific, but can be
seen with any highly parallel application, that
starts tasks doing simultaneous output on stdout /
stderr.

A possible resolution of the problem would be to
redirect output of each task in a temporary file
(joined stdout and stderr to preserve the order of
messages), output the contents of this file at
task end and remove the temporary file.
