71Another useful bit of functionality is the Linux eventfd, which is useful
72for faster signal handling (don't care) and intra-thread communications
73(mostly useful for embedding). Kernel support for this will be probed at
74runtime, but your libc must contain the necessary wrapper. Glibc 2.7 and
75later should have this wrapper.
