New versions of s6-tcpserver4d and s6-tcpserver6d
- both now use posix_spawn when available - s6-tcpserver4d uses avltree for logarithmic lookups - s6-tcpserver6d still has the linear lookup - the point was to benchmark linear vs logarithmic, but the fork() overhead overshadowed everything - now with fork() out of the way, I'm going back to benchmarks Signed-off-by: Laurent Bercot <ska@appnovation.com>
