- Check and report write(2) errors.
- Issue a single writev(2) call instead of multiple write(2)s.
This change improves the inefficiencies introduced when echo
went on an stdio diet.
The following figures are for echoing 1000 arguments.
original stdio-based echo:
0.01 real 0.01 user 0.00 sys
before:
0.05 real 0.00 user 0.04 sys
after:
0.01 real 0.00 user 0.00 sys
