------------------------------------------------------------
[Stalled]

* dc/update-INSTALL-WIN32.md (otp) (2010-09-19) 1 commit
 - Doc update to latest dependencies & how to compile with free VS2008
Express (8e8061c)

Waiting for an update by the topic author.

* jn/gen_stream (stdlib) (2010-09-05) 5 commits
 - Use erlang:process_info(Pid, links) to determine if gen_stream
managed worker processes are leaked (b2386df)
 - Move gen_stream internal process test to after termination of
gen_stream parent (f1d8a97)
 - Add calls to code loader in every test to verify code loader still
running (ac6cbba)
 - Track gen_stream processes directly for accurate test results (38a4083)

 . Add new gen_stream behaviour for efficiently consuming serial

This topic branch has a failing test case:

shell_SUITE:start_restricted_from_shell;
    We have now tested with and without this topic branch and when
    it is present that test case fails. We consider it proved
    to be guilty. The test case does not fail when run standalone
    so it seems to be tricky... Also, some of its own test cases
    fail sporadicly.

Action expected from: Topic author.

* jp/dependencies_makefile (compiler, erts) (2009-12-14) 1 commit
 - Add dependencies Makefile generation to erlc(1) and compile(3) (4945add)

review of the implementation.

Action expected from: Björn Gustavsson (the reviewer)

* sf/erts_de_busy_limit (erts) (2010-10-22) 1 commit
 - Add flag-based setting for 'erts_de_busy_limit' constant (e3da5a0)

This topic branch has multiple issues described in this email:

http://www.erlang.org/cgi-bin/ezmlm-cgi?3:mss:1303:201008:ldciadjdmjednikemjch

Action expected from: Topic author.
