I think I found the first case of Sun's merged buffercache/vm
system ``showing itself''.

A trace of ldconfig shows this:

mmap (0, 1048576, 0x3, 0x80000001, 3, 0) = 0xf75f0000
getpagesize () = 4096
ftruncate (3, 4096) = 0
<we dump core here>

I bet right after the ftruncate it attempts to access 0xf75f0000
+ N (4096 > N >= 0).

Oh bugger.
