Introduction to libsigsegv

libsigsegv is a library for handling page faults in user mode. A page fault occurs when a program tries to access to a region of memory that is currently not available. Catching and handling a page fault is a useful technique for implementing pageable virtual memory, memory-mapped access to persistent databases, generational garbage collectors, stack overflow handlers, and distributed shared memory.
