Summary

0000902: Net::Telnet and Net::Appliance::Session use alarm() for timeout which is incompatible with threaded perl

Description

This is a problem because we need to set a global sig alrm handler and we have no context information to properly report the error. Also, even after the alarm, the telnet call will hang until the low-level socket times out which takes 2-3 minutes..

Net::Appliance::Session uses Net::Telnet internally.

Reported upstream: https://rt.cpan.org/Public/Bug/Display.html?id=54415 [^]

This bug will track upstream's status.
Another bug will be open for the workaround.

Notes
(0001551) obilodeau (reporter) 2010-05-05 13:44	This bug is mitigated in the upcoming 1.9.0. Upstream is unlikely to fix so the recommendation in 0000909 would be the way to go.
