We can just EOF the pipe, and instead rely on per-class
error handling to deal with uncommitted transactions and
what not.

Usage summary:

	lei add-external /path/to/v1-or-v2-inbox
	lei add-external /path/to/another-inbox-or-ext-index
			# URLs aren't supported, yet :<

	lei q SEARCH TERMS GO HERE... # pager should open with JSON output

For faster startup time than what Inline::C can give:

	apt-get install libsocket-msghdr-perl # Socket::Msghdr

Having neither Inline::C nor Socket::Msghdr means parallel
queries won't work.

I went back-and-forth on a bunch of things but ultimately gave
up trying to support IO::FDPass since it got too fragile and
difficult to test with the work-queue distribution.

The pager runs from the client process (if using Socket::MsgHdr
or Inline::C), now.  It took at fair amount of work from my slow
brain to get pager shutdown to be instantaneous, though queries
which haven't output anything aren't easily interruptible...

The wq_* IPC stuff will be reused in the normal read-only
WWW/IMAP search at some point, too.

Eric Wong (22):
  lei query + pagination sorta working
  lei q: deduplicate smsg
  ds: block signals when reaping
  ipc: add support for asynchronous callbacks
  cmd_ipc: send FDs with buffer payload
  ipc: avoid excessive evals
  ipc: work queue support via SOCK_SEQPACKET
  ipc: eliminate ipc_worker_stop method
  ipc: wq: support dynamic worker count change
  ipc: drop -ipc_parent_pid field
  ipc: DESTROY and wq_workers methods
  lei: rename $w to $wpager for warning message
  lei: fix oneshot TTY detection by passing STD*{GLOB}
  lei: query: ensure pager exit is instantaneous
  ipc: start supporting sending/receiving more than 3 FDs
  ipc: fix IO::FDPass use with a worker limit of 1
  ipc: drop unused fields, default sighandlers for wq
  lei: get rid of client {pid} field
  lei: fork + FD cleanup
  lei: run pager in client script
  lei_xsearch: transfer 4 FDs internally, drop IO::FDPass
  lei: query: restore JSON output overview
