I'm opposed to strlcat/strlcpy in the first place. It
usually starts long debates, and opponents usually argue
that it serves no real purpose, and gives a shallow feeling
of safety when there really is none. Proponents of strlcpy
are quite religious about spreading it quickly. For example,
there was a heated discussion about adding strlcpy to GNU
libc, after which glibc maintainers to ignore them.

I propose to do the same thing in Python.

If they want people to use their code why do they put that
stupid clause in the license?  How annoying.  Attached is
a strlcpy function that I wrote based on the man page:

Do whatever you like with it. :-)  I would appreciate it if
someone would review the code however.  There are a number
of corner cases that are easy to screw up.

Strictly speaking, binary Python distributions would be
required to contain a copy of the entire license for that
file. I don't like that.

I'm attaching a patch from Alex Martelli; haven't reviewed 
it, and don't expect to before 2.2 final is released.

Time for PyOS_strlcat() and PyOS_strlcpy() ? Looking at the web-site it seems that we could simply copy the 
code into the Python distro. I'd then suggest to bundle all the string helpers into a new file: e.g. mystrapis.c.
