This library attempts to provide reliable pollyfills for functionality that isn't implemented on all platforms, for example
fexecve, as well as providing non-atomic versions of functions like
pipe2, and other miscellanea like
seal to make a file descriptor read-only thus suitable for
palaver = "Platform Abstraction Layer" / pa·lav·er n. – prolonged and tedious fuss.
It's currently used on unix-family systems; most Windows functionality is TODO.
