R devel - Sep 2003 - RAqua too hungry of cpu time

It seems that RAqua consumes too much cpu time when doing nothing.
I can't see exactly why this is happening. We have few days to fix this 
up. Any idea (after having look at the code) would be fine.

Well, it happens exactly what the code says ;). RAqua is spending all 
the time in those loops like this one:

    while(!InputFinished & !HaveBigBuffer)
         Raqua_ProcessEvents();

(This one comes from Raqua_ReadConsole)

Since in Raqua_ProcessEvents you simply call ReceiveNextEvent with 
kEventDurationNoWait, the function returns almost immediately and is 
called again ... so in effect you are hogging 100% CPU. I'd suggest 
using either some sensible timeout or kEventDurationForever.

Cheers,
Simon
