We have a couple of patch series we’re working on (ObjectDB/Read-Object,
Watchman integration) where we could use the ability to have a
background process running that can accept multiple commands thus
avoiding the overhead of spawning a new process for every command.
The ability to do this was added in:
Commit edcc85814c ("convert: add filter.<driver>.process option",
2016-10-16)
keeps the external process running and processes all commands
but it is integrated into the convert code. This patch series takes the
code from convert.c and refactors it into a separate “sub-process”
module so that we can centralize and reuse this logic in other areas.
Once the code was refactored into sub-process, convert.c was updated to
use the new module.

pkt-line: add packet_write_list_gently()
sub-process: refactor the filter process code into a reusable module
convert: use new sub-process module for filter processes
