This is actually a bit of a side project which involves using gembuilder 
for C. If you use its "thread-safe API", it forces you to go via RPC. (I 
guess this is so several different RPC gems can be started, each running 
its own single thread on the server.) It is a "developing experiment" 
though ;-) and that may have been the wrong choice of API.

Good to know, thanks.

Thanks. I have been doing this with a bare-bones gemstone install, not 
gsdevkit or the shipped stuff in $GEMSTONE/seaside. AFAIK 
$GEMSTONE_LOGDIR is a gsdevkit thing? I will go investigate.
