A Process::Status contains information about a system process.
Thread-local variable $? is initially nil. Some methods assign to it a Process::Status object that represents a system process (either running or terminated):
`ruby -e "exit 99"` stat = $? # => #<Process::Status: pid 1262862 exit 99> stat.class # => Process::Status stat.to_i # => 25344 stat.stopped? # => false stat.exited? # => true stat.exitstatus # => 99

The Process::UID module contains a collection of module functions which can be used to portably get, set, and switch the current process’s real, effective, and saved user IDs.
The Process::GID module contains a collection of module functions which can be used to portably get, set, and switch the current process’s real, effective, and saved group IDs.
The Process::Sys module contains UID and GID functions which provide direct bindings to the system calls of the same names instead of the more-portable versions of the same functionality found in the Process, Process::UID, and Process::GID modules.
