I pushed the small preliminary patches.  Here's a rebase of the main patch.

Commits

  1. Remove unneeded volatile qualifiers from postmaster.c.

  2. Fix WaitEventSetWait() buffer overrun.

  3. Refactor DetermineSleepTime() to use milliseconds.

  4. Use WaitEventSet API for postmaster's event loop.

  5. Allow parent's WaitEventSets to be freed after fork().

  6. Don't leak a signalfd when using latches in the postmaster.

  7. Add WL_SOCKET_ACCEPT event to WaitEventSet API.
