This is, I presume, for Linux systems without systemd and pam_env.so?
Because, the vast thing that is systemd, takes care of mounting a /run
and creating user dirs. inside it; and pam_env.so can read
/etc/environment{,.d/*} and /etc/security/pam_env.conf files where you
can set these system-wide env. vars.

I haven't gone through your code in detail, but, I noticed these small
issues:

Line 40: a_RUNTIME_DIR_BASE_MODE should be mode 0700. All dirs. under
/run are set that way, I think.

Line 77: That ORing is a bit of an odd way to set that buffer size (if
that isn't a typo). Maybe comment is as such?

There should be a removal of the dirs. on the user's final session
logout, I think.
