_virtualenv ignored; close store and tlog on both SIGTERM & SIGINT
rewrite last tlog entry with annotation when closing;
log what's going on in failing system test.
--strip-tlog
moving tlog tools outside main
system test for tlog markers;
--mark-tlog feature in cmd line
verify marker @ startup time, and set a new one after that,
but not in all cases
fix testcases.
log_extra changed the way a string option is printed
so the tests that use --dump-store needed to be adapted too
quick tests succeed
made a path for exit codes to leave the process
first example is 42
