### misc

- handle signals using the self-pipe trick (nothing else seems better nor as portable)
- close the connection and log when we receive too big messages
- decide then explicitely document what the max message size should be
- rx message buffer should be small but should grow if required
- some functions are not exposed in the bindings, mostly functions related to switching

### makefile

- release
- distribution

### documentation

- document the two ways to use LibIPC: either within some Zig code or through the bindings
- manpages for ipcd, tcpd, pong, pongd

### src/exchange-fd.zig

- still very WIP, even though it works as expected
- recvmsg is a very *stupid* copy of the sendmsg fn, **EXPECT ERRORS** (if used outside libipc)
- at least one memory error when using Cmsghdr (see below)
