Assuming they also release their C library sources, then the answer
is obvious: study the code until you understand how signal handling
works in the C library, including interaction with alternate signal
stacks and threads. Then you'll be in position to either suggest code
to safely override sigaction, or to declare this a lost cause (if
their C library has insurmountable problems).
