Delegates all {Gem::Resolver::Molinillo::ResolutionState} methods to a ‘#state` property.
Returns the number of malloc() allocations.
Only available if ruby was built with CALC_EXACT_MALLOC_SIZE.
This method is equivalent to new_start(Date::ITALY).
Top level install helper method. Allows you to install gems interactively:
% irb >> Gem.install "minitest" Fetching: minitest-3.0.1.gem (100%) => [#<Gem::Specification:0x1013b4528 @name="minitest", ...>]
If src is not same as dest, copies it and changes the permission mode to mode. If dest is a directory, destination is dest/src. This method removes destination before copy.
FileUtils.install 'ruby', '/usr/local/bin/ruby', mode: 0755, verbose: true FileUtils.install 'lib.rb', '/usr/local/lib/ruby/site_ruby', verbose: true

Waits for all children, returning an array of pid/status pairs (where status is a Process::Status object).
fork { sleep 0.2; exit 2 } #=> 27432 fork { sleep 0.1; exit 1 } #=> 27433 fork { exit 0 } #=> 27434 p Process.waitall
produces:
[[30982, #<Process::Status: pid 30982 exit 0>], [30979, #<Process::Status: pid 30979 exit 1>], [30976, #<Process::Status: pid 30976 exit 2>]]
Returns the size of memory allocated by malloc().
Only available if ruby was built with CALC_EXACT_MALLOC_SIZE.
Adds a post-install hook that will be passed an Gem::Installer instance when Gem::Installer#install is called
Adds a post-installs hook that will be passed a Gem::DependencyInstaller and a list of installed specifications when Gem::DependencyInstaller#install is complete
Adds a post-uninstall hook that will be passed a Gem::Uninstaller instance and the spec that was uninstalled when Gem::Uninstaller#uninstall is called
Adds a pre-install hook that will be passed an Gem::Installer instance when Gem::Installer#install is called. If the hook returns false then the install will be aborted.
