BeOS port

    Hi alls
I'm working on a port of postgres on BeOS (www.be.com). BeOS is not 
a real UNIX, but it provide a subset of the posix API. At this stage 
I've a working version ofit. But since 6.4.2, I've a lot of problems 
(dynamic loading doesn't work any more...) with the fact that 
postgresmain is call directly instead of the old exec method. BeOS 
really don't like to do a lot of thing after a fork and before an exec 
:=(. I would like to know how hard it would be to add the exec call. As 
I understand it, I have to get back all global variables and shared 
memory and perhaps doing something with sockets/file descriptors ? I've 
a ready solution for shared memory but I need some help regarding the 
others points.
Any will really help me.
