/* ruby-prof tracks the time spent executing every method in ruby programming.
The main players are:
profile_t - This represents 1 profile.
thread_data_t - Stores data about a single thread.
prof_stack_t - The method call stack in a particular thread
prof_method_t - Profiling information about each method
prof_call_tree_t - Keeps track a method's callers and callees.
The final result is an instance of a profile object which has a hash table of
thread_data_t, keyed on the thread id. Each thread in turn has a hash table
of prof_method_t, keyed on the method id. A hash table is used for quick
look up when doing a profile. However, it is exposed to Ruby as an array.
Each prof_method_t has two hash tables, parent and children, of prof_call_tree_t.
These objects keep track of a method's callers (who called the method) and its
callees (who the method called). These are keyed the method id, but once again,
are exposed to Ruby as arrays. Each prof_call_into_t maintains a pointer to the
caller or callee method, thereby making it easy to navigate through the call
hierarchy in ruby - which is very helpful for creating call graphs.
