Keystrokes of GNU Readline will timeout it with the specification of “keyseq-timeout” when waiting for the 2nd character after the 1st one. If the 2nd character comes after 1st ESC without timeout it has a meta-property of meta-key to discriminate modified key with meta-key from multibyte characters that come with 8th bit on.
GNU Readline will wait for the 2nd character with “keyseq-timeout” milli-seconds but wait forever after 3rd characters.
Notifies all registered listeners for event of a status change of tuple.
Unregister the Symbol command as a gem command.

Indicated, based on the requested domain, if local gems should be considered.
Return a list of the gem specifications in the dependency list, sorted in order so that no gemspec in the list depends on a gemspec earlier in the list.
This is useful when removing gems from a set of installed gems. By removing them in the returned order, you don’t get into as many dependency issues.
If there are circular dependencies (yuck!), then gems will be returned in order until only the circular dependents and anything they reference are left. Then arbitrary gemspecs will be returned until the circular dependency is broken, after which gems will be returned in dependency order again.
Compacts Marshal output for the specs index data source by using identical objects as much as possible.
Ensure that the dependency is satisfied by the current installation of gem. If it is not an exception is raised.
Extracts only the bin/ files from the gem into the gem directory. This is used by default gems to allow a gem-aware stub to function without the full gem installed.
This is ported over from the yaml_tree in 1.9.3
