[issue28946] AttributeError: module 'signal' has no attribute 'SIGALRM'

[dd]

New submission from dd:

When I try to run the example at the very end of the signal documentation page [https://docs.python.org/3/library/signal.html#example] I get the error from the title: 
AttributeError: module 'signal' has no attribute 'SIGALRM'

The same thing happens for SIGINT, which is what I was trying to use in the first place.

I found the comment that many things in signal have been turned to enums [https://docs.python.org/3/library/signal.html#module-contents] but they don't seem to be documented anywhere.

I'm not sure if this is an actual bug or if these enums are just not documented, but It would be great if someone could look into this.

I run an up-to-date Manjaro Linux (an Arch-based distro) and Python 3.5.2 (default, Nov  7 2016, 11:31:36) 
[GCC 6.2.1 20160830]

Let me know if anything is unclear.
