Package ruby-posix-spawn: Information

Ruby process spawning library.

fork(2) calls slow down as the parent process uses more memory due to the need
to copy page tables. In many common uses of fork(), where it is followed by one
of the exec family of functions to spawn child processes (Kernel#system,
IO::popen, Process::spawn, etc.), it's possible to remove this overhead by
using special process spawning interfaces (posix_spawn(), vfork(), etc.)

The posix-spawn library aims to implement a subset of the Ruby 1.9
Process::spawn interface in a way that takes advantage of fast process spawning
interfaces when available and provides sane fallbacks on systems that do not.
