Using a mutex, yes, that's what I thought as well. Btw, CPU_TIME gives values
per process and does not bother with threads. DTIME probably wants to do the
same?

While at it, a common time aquisition function for all three, CPU_TIME, DTIME
and ETIME, would be useful. Currently, ETIME has an implementation separate
from CPU_TIME -- but both use getrusage().
