I was just playing around with MallocLogFile as environmental setting in .MacOSX/environment.plist, naturally, on the computer I'm typing this, but I know NetBSD has similar , so I'm suggest seeing how those perform when logging malloc's, and perhaps compare that.
Also, perhaps with any MallocScribbles, or similar...

Any thoughts on the pros and cons of

# cgdconfig -s cgd0 /dev/sd0e adiantum 256 < /dev/urandom
# dd if=/dev/zero of=/dev/rcgd0d bs=64k progress=512
# cgdconfig -u cgd0

vs

# dd if=/dev/urandom of=/dev/rsd0e bs=64k progress=512

?

Cheers,

Patrick
