Executing signal handlers at known points

Question

What I want to do is to prevent signals from interrupting my application. At known points, for example, before making a system call, I will check for pending signals and call their handlers. In other words, I want to defer signal handling to known points in the code.

Any idea how this can be done? Can this be done in user-space or kernel modification will be required?
