I don't think that "No child process" is locale sensitive, but on some platforms could produce "No children" instead (citation). However, you can ignore the error message's text by remembering that $! is a dual-valued variable; In string context it returns the error message. In numeric context, it returns the error number, which can be tested against the &Errno::ECHILD constant (Errno).

Or you can use %! in some variant on the example code shown in Errno's POD:

# A variation on Errno's POD example:
use Errno qw( ECHILD );

# ........

if ( not close $something ) {
  if( not $!{ECHILD} ) {
    die "Houston, we have a problem: $!";
  }
  else {
    # Silence is golden; ECHILD is silent.
  }
}
