212Another useful bit of functionality is the Linux eventfd, which is useful
213for faster signal handling (don't care) and intra-thread communications
214(more relevant). Kernel support for this will be probed at runtime, but
215your libc must contain the necessary wrapper. Glibc 2.7 and later should
216have this wrapper.
