Hi Patrick,

I have been adding parts of your patch to Dazuko's HEAD development. I 
have already added dup() and dup2() support. This will be included in 
the official 2.0.4 release. However, I will be adding the other hooks 
with ON_WRITE events in the REL_21 branch. In my opinion, supporting 
ON_WRITE events is a big step.

dup() and dup2() make an excellent improvement to support the ON_OPEN, 
ON_CLOSE events. This is why I have included them in HEAD. I also 
implemented your patches differently so that hashes do not have to be 
exported from dazuko_xp. My implementation also will work for kernels 
that allow kernelspace context switching (even though FreeBSD 4 actually 
cannot do this).

Another change in my implementation is that I post events before the 
system calls. This gives the application a chance to deny dup() and 
dup2() calls.

I will most likely be porting this new code to FreeBSD 5 and Linux 
before adding the ON_WRITE work. These new changes have really improved 
Dazuko for FreeBSD 4 and I want the other platforms to benefit as well.

Thank you for all your work!
