I remember your posting, but not the details. Did it relate to glibc's malloc
and how long it took to free things? If so, surely benchmarking using perl's
malloc would work with earlier glibc's?

Anyway, on the two Debian systems I tested:

nick@penfold:~/5.8.0-i-g/t$ ls -l /lib/libc.so.6
lrwxrwxrwx    1 root     root           13 Jan  2 08:46 /lib/libc.so.6 -> libc-2.3.1.so
nick@mirth:~$ ls -l /lib/libc.so.6 
lrwxrwxrwx    1 root     root           13 Jan  7 16:20 /lib/libc.so.6 -> libc-2.3.1.so

And (obviously) the FreeBSD has BSD's libc

Thanks for the reminder. It's only good luck that I (well Richard) had 2.3.1
on them.
