There is no more Solaris buildbot, there is no useful information to debug this 
issue, so I close the issue.

Is Solaris 9 supported as I can't find any buildbots for it?

Test results for sources pulled from the mercurial repository: they hang in the

[issue18605] 2.7: test_threading hangs on Solaris 9

[Maciej Bliziński]

New submission from Maciej Bliziński:

Python version: 2.7.5
OS: Solaris 9
Architecture: sparc

Looks similar to Issue5114 and Issue6643 but both are now closed.

It seems specific to Solaris 9, I'm not seeing this issue on Solaris 10.

The symptom is that test_threading hangs indefinitely (tested overnight) . When 
running pstack on the process, I'm seeing this:

[Antoine Pitrou]

Antoine Pitrou added the comment:

 Please at least run test_threading in verbose mode, to know which test 
 exactly hangs: ./python -m test -v test_threading

Sorry, I meant: ./python -m test.regrtest -v test_threading

Antoine Pitrou added the comment:

Please at least run test_threading in verbose mode, to know which test exactly 
hangs: ./python -m test -v test_threading

Also, please try with the default branch too (which will become 3.4 when 
released). Instructions to check out the code:
