It might not be a satisfying answer... but go for fork(). I recommend this option - no kernel changes involved... unless someone wants good performance when executing memcached. fork() tends to replace vfork() in similar software. And while there, calling other functions than exec() after vfork() is less portable than vfork(). TSan notes that this is/was Undefined Behavior and workaround issues in openjdk (which closes file descriptors) with wrapping fork().
