&gt; To reduce the performance impact of syscalls without modifying application software, exceptionless&#x2F;asynchronous syscalls have been demonstrated. With the regular syscall interface, the userspace process requests a syscall by executing a special software interrupt instruction to cause a context switch to the kernel. The arguments for the syscall are put in the general-purpose registers. The exceptionless syscall model requires small modifications to the libc and the kernel: when a syscall is requested from the application program, the libc places the syscall’s arguments in a special page of memory (“syscall page”) and switches to another user-level thread.<p>It would be great to have standard API for this, let&#x27;s say fake mux syscall that would queue other syscalls and trigger them all at once after some period of time.
