This is not really what I am asking for.
Our current situation is that asan (ab)uses undocumented and unsupported
features of
glibc that glibc periodically changes, and has the full right to do so.
What I am asking for is to have a set of documented and supported features
that will support asan
and that will be tested as part of the main glibc test suite.
(https://sourceware.org/glibc/wiki/ThreadPropertiesAPI is my old attempt,
but it didn't get attention)
