== FORK ================================================================
- _INTERNAL_trust einbauen
- unique counters für contexte, ergo global packet ids unterstützen
see also http://about.psyc.eu/Routing 2.2
- einmaliges rendern von psyc paketen ohne psycd realisieren,
idealerweise auch im sendmsg() statt in group/route, und zwar so:
// <lynX> new idea: for future use, psyc packets need to be cached
// according to their packet id anyway, so whenever the _count is
// the same as the one before, sendmsg() can optimize by using
// the last cached outgoing packet of this context. this way the
// render-only-once optimization can move down into sendmsg()
* das problem der dangling delivers bei destructeten psyc servern.
- die drittbeste lösung ist im begriff abgeschafft zu werden:
psycd ist allerdings noch nicht vollständig ausgemerzt
: die zweitbeste lösung macht FORK derzeit mit psyc_deliver() in der lib
+ die beste lösung wäre psyc/server und active.c wieder in ein
gemeinsames circuit.c zusammenzuführen. der versuch mal schnell active.c
zum neuen server zu machen ist gescheitert, da active.c schon eine weile
lang server.c gar nicht inheritet. letztlich ist diese operation nicht
überstürzenswert, lieber vorsichtig planen - etwa in dem wir für das neue
mixgerät aus active, server und circuit erstmal ein temporäres newct.c machen
