Description:   Opened: 2008-12-19 12:46 0000 
This is really weird bug. After I've disabled failing tests in bzr tests pass
but then emerge process hangs after:

>>> Completed installing bzr-1.10-r1 into /vt/portage/tmp/portage/dev-util/bzr-1.10-r1/image/

hang... 100% cpu load.

bzr-1.10-r1.ebuild

to reproduce the problem run
FEATURES=test emerge -v bzr

I've tried to reduce number tests but failed: at some point I've reduced to 4
tests branches (by branches I mean blackbox.*, )test_http.* and so on - tests
having same beginning in their name) but then after I've tried to reduce to
two, emerge passes. When I back to 4 tests it stopped to hang too but when I
back to all tests it hangs.

And forgot to note. To avoid tests failures you need net-misc/curl-7.18.2 and
dev-python/pycurl-7.16.4... I have not checked if I disabled all tests for
newer versions of this libraries.

remove unnecessary regex patterns that cause problems

The test suite uses \r to rewrite the same line thousands of times and this
triggers a performance issue in the regex patterns that are used to search the
build log for QA issues.

Thank you very much Zac. It works.

This is fixed in 2.1.6.2 and 2.2_rc18.
