You probably still want a global limit, or else malicious sites can DoS your
entire OS by spawning workers in many synthetic domains. Making the limit
per-eTLD instead of per-domain would help a bit, but maybe not very much.
Same goes for other kinds of resources; there's no really perfect solution
to DoS attacks against browsers, AFAICT.
