	Pisu mozna uplne mimo protoze Windows nerozumim, ale jeste existuje
flag FD_CLOEXEC, kterym lze rict, ze tento filehandle se nema predavat
novemu programu spoustenemu pres exec() (coz je zrejme neco co system()
vola uvnitr). Hmm, vlastne - nechces ty exec misto system 1, ... ?

	Neco jako

my $flags = fcntl(STDOUT, F_GETFD, 0);
$flags &= ~FD_CLOEXEC;
fcntl(STDOUT, F_SETFD, $flags);

a pak

exec $prikaz, $arg1, $arg2, ...;
