OK. Is there any example code that uses sysctls in this way?
Thanks ;)

Aah. This isn't quite what I lust for: Is it possible to get a *log* of
allocation requests rather than aggregate sums or averages

I'm trying to build a preforked and threaded server. When it comes to
the threading part it seems that non-preemtive threads have a lot of
benefits if the server is a statefull-server.
What I'm trying to say is that the server is not going to do a lot of
computation for each request. The server

Howdy!
I've run into a situation where I need to have two differing
implementations of a library (both are from the ports collection)
installed on the same machine... by default both implementations get
installed with the same name (but in different locations) which causes a

lets say, hypothetically, that i have an ioctl interface to my device
driver that takes a buffer that looks something like:
struct {
int length;
char *buf;
} mystruct;
and lets say, hypothetically, that i wanted to dma directly
to/from 'buf'. how would i do that?
i've tried doing vtophys o

Is there anyway I can figure out where exactly this is happening, maybe

Is this similar to the following kernel configuration?
options TCP_DROP_SYNFIN #drop TCP packets with SYN+FIN

This is happening in a call to free() ;; the memory being freed is either
not actually allocated or is somewhere that your programs memory does not
contain (ie address out of range).
Use mxgdb, ddd, or gdb to show all things things and step through the
executiong.
