I don't think there are any plans to move into that direction at all.
There is ~zero demand for it.

Basically: yes, if you support the notion of having a non-threaded libc at
all/by default.

Consider all the state kept in libc, which is different in a threaded from
a non-threaded world. At pthread load time, you would have to convert the
state for all cases correctly, completely, and without deadlocks.

The only way to do this without brain damage is to have libc always use
the threaded functions thus causing a major performance penalty for non 
threaded applications.
