5/9 has been a long-time coming, a few other small things, too.
The diff stat for lib/ alone shows a nice reduction
Eric Wong (9):
doc: lei-security: some more updates
listener: switch to level-triggered epoll
daemon: make SO_ACCEPTFILTER a shared variable
ipc: run Net::SSLeay::randomize
ds: simplify signalfd use
inbox: inline and eliminate git_cleanup
inbox: keep DB handles if git processes are live
ds: inline set_cloexec
doc: lei-daemon: new manpage
