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);
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.
spawn by default.
