Constant lookup in Ruby can happen lexically or through the ancestry tree of the receiver(a class or module). You can identify which lookup rules are being applied by the context you're in or by the syntax being used to define a class or module.

A class body that is defined as class A::B::C; …; end will lookup constants through the ancestry tree when a constant is evaluated in its class body. Anytime you see A::B::C being used as syntax to define a class or lookup the value of a constant the ancestry tree is being used for the lookup.

>  - In ruby 1.8.x, what is the functional difference between rb_thread_schedule and rb_thread_select?

rb_thread_schedule() is the guts of the thread scheduler, it traverses
over the linked list of threads (several times) to find the next one
to switch into. The function is long (250 lines) and messy, and covers
all the combinations of thread status (RUNNABLE, TO_KILL, STOPPED,
KILLED) and wait state (FD, SELECT, TIME, JOIN, PID).

If there are no threads doing i/o or waiting on a timeout,
rb_thread_schedule() picks another thread from the list (considering
