I've seen Judges issue bench warrants and have Sheriff's go out and pick up jurors who did not show up. Doesn't happen often, but I have seen it happen.
I guess its different in different jurisdictions, but in my experience issuing a bench warrant for someone skipping jury duty is standard operating procedure. It does tend to overburden a busy sheriff's office, but most sheriffs would have a round up day every month or so for these type warrants.
The juror would come in, get lectured by the judge, put on duty for the next docket and let go.
