Hi Florian,

The main use case is to intercept Windows system calls of an application
running over Wine. While Wine is using an unmodified glibc to execute
its own native Linux syscalls, the Windows libraries might be directly
issuing syscalls that we need to capture. So there is a mix. While this
mechanism is compatible with existing libc, we might have other
libraries executing a syscall instruction directly.
