New Revision: 12262

Modified:
   main/branches/2.1.6/pym/portage/__init__.py
Log:
Bug #251616 - Inside _check_build_log(), remove unnecessary .* patterns from regular
expressions. These patterns trigger extreme performance issues when matched against
extremely large lines such as those produced by dev-util/bzr test suite when it
uses \r to rewrite the same line thousands of times. (trunk r12259)
