[h323plus] H323AudioCodec::SetRawDataHeld

Hi,
my question might be stupid but can someone explain why a mutex is
used in the SetRawDataHeld method :
BOOL H323AudioCodec::SetRawDataHeld(BOOL hold) {
PTimedMutex m;
m.Wait(50); // wait for 50ms to avoid current locks
IsRawDataHeld = hold;
m.Wait(50); // wait for 50ms to avoid any further locks
return TRUE;
}
I have another problem concerning codecs. Codecs sleep during read
and write (within ReadRaw et WriteRaw) keeping rawChannelMutex locked
and they lok it again immediately after signalling.
I encouter thread starvations (or at least very long time before
getting method called) when I try to call addFilter or SwapChannel on a
running codec.
This behavior can, for instance, prevent me from holding a call.
Does anyone have this same problem ?
Thanks for your help,
Sebastien
