valgrind

[Mouse <mouse%Rodents-Montreal.ORG@localhost>]

http://wiki.netbsd.org/projects/project/valgrind/ sketches a project
for porting valgrind, but gives tech-kern as its contact address.
Surely that's not right?

In passing, the difficulty will vary, substantially I expect, with the
port(s) it's targeted for.  I spent a while trying to implement
valgrind on the NetBSD/sparc I use and ended up collapsing that effort
into my userland SPARC emulator instead; handling a restore in the
delay slot of a jmpl, a common thing in function epilogues, looked like
more of a headache than adding the functionality to the emulator.
(It's found one bug in libc already, back in July 2021 IIRC.)

Perhaps I just need a better approach....
