* test/lib/envutil.rb (Test::Unit::Assertions#assert_no_memory_leak):
NO_MEMORY_LEAK_ENVS is moved to Memory::NO_MEMORY_LEAK_ENVS to reduce child executions during test-all on Solaris. * test/lib/memory_status.rb (Memory::NO_MEMORY_LEAK_ENVS): ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@51028 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
