[$] Emulating Windows system calls in Linux

The idea of handling system calls differently depending on the origin of eachcall in the process's address space is not entirely new. OpenBSD, forexample, disallows system calls entirely ifthey are not made from the system's C library as a security-enhancingmechanism. At the end of May, Gabriel Krisman Bertazi proposeda similar mechanism for Linux, but the objective was not security atall; instead, he is working to make Windows games run better under Wine. That involves detecting and emulating Windows system calls; this can bedone through origin-based filtering, but that may not be the solution thatis merged in the end.
