Run - Perl extension for to start programs in background

  use Run;
  $pid = spawn 'long_running_task', 'arg1', 'arg2' or die "spawn: $!";
  do_something_else();
  waitpid($pid,0);

The subroutine spawn is equivalent to the builtin system (see system LIST in perlfunc) with the exceptions that the program is started in background, and the return the pid of the kid.

Returns 0 on failure, $! should contain the reason for the failure.

Exports spawn by default.

open FH, ">&=FH1" creates a "naughty" copy of FH1. Closing FH will invalidate FH1.
