Module Name:    src
Committed By:   sjg

Modified Files:
        src/usr.bin/make: job.c

Log Message:
Skip setting wantToken.

polling the job token pipe adds a lot of overhead
for little gain.
For now, just leave wantToken=0

And avoid busy waiting when no tokens are available and
no jobs are running.
