scratchpad for the development of iemnet
========================================
speed & syslocks
================
one bottleneck right now is the synchronisation with Pd's
main thread to register a clock callback.
doing a sys_lock() whenever a package arrives will slow down things immensely.
alternatives:
no sys_lock(): will eventually crash Pd (no option)
use sys_trylock(): this might eventually fail to notify Pd of newly arrived
packets (bad for throughput)
external polling: no syslock needed at all, but more complicated
keep track of clock_callback: "notified" flag tells us, whether we have already
sent a notification which has not yet been handled...no need to notify again
#4 looks most promising
tests for tcpclient/server:
client disconnects -> server should get notified
server disconnects -> client should get notified
client crashes -> server should disconnect
server crashes -> client should disconnect
