commit d3901b506e85fd7b4dbdcbcd3f187a61346079a8

try to improve http-server startup/teardown in regress

Let tests fail if http-server fails to start up within 5 seconds.
Make http-server report its process ID in its log file such that
tests can kill it by PID.

Prompted by semi-regular failures on my arm64 regress builder.
