Comment:

 I am not sure I understand all the perl constructs used.

 In line 35 a select is used to make $lines the current filehandle. However
 according to [http://perldoc.perl.org/functions/select.html] select sets
 the default output filehandle, while $files is used for input (of the
 script's output). So it seems to make no sense to set its buffering (see
 [http://perldoc.perl.org/perlvar.html]). <Nitpicking>Is $line_number
 actually used anywhere? It is not a drop in replacement since it adds a
 bit of extra output telling the user which script runs. Not sure how
 helpful it is in a parallel build.</Nickpicking> (yes I have read the "How
 to review patches guide" hence the tags).

 Otherwise the patch looks fine.
