Does it mean that the CLONE_SIGHAND bit in the mask does not
have any effect
in 2.2.12? I'm using 2.2.16, so I don't know how it works in
2.2.12.

If this approach is not supported in earlier kernel, I think
another
solution is to let each Thread register its handler to the
thread manager
(the Thread class) and when a certain signal is raised, the
manager
will lookup a table of registered handlers and call each of
them.
This table is index by signal number. However, this approach
requires
the manager to define handler for all possible signal
number.
