Sure.  I was being defensive because the manpage says:

/proc/self

    This directory refers to the process accessing the /proc
    filesystem, and is identical to the /proc directory named by the
    process ID of the same process.

which I thought meant the PID rather than the TID.  However, the page
is misleading: I just checked and /proc/self refers to the TID.  (Not
that it really matters, as the mappings will mostly be the same
anyway.)

Fixed.

By the way, I have a good regression test for this.  Should I submit
that too?

Andrew.
