Assign to myself, since my patches are in the possible regression range.

[Kershaw Chang [:kershaw]]

The crash all happens on osx and somehow related to pr_poll.
Dragana, from my vague memory, it seems you mentioned that there is a problem related to pr_poll on osx.
Could you remind me again what it is about? Thanks.
