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
