print returning EINTR

[vsespb]

There is a bug in perl 5.14 , which was fixed in later versions:
https://rt.perl.org/rt3//Public/Bug/Display.html?id=119097 (fix and testcases included)

Problem is that print(), read() can fail if interrupted. ( testcase for read http://www.perlmonks.org/?node_id=1026468 )

Perl code, that run into this bug, can mistakely decide that there is EOF of data coming from pipe/socket, this can lead to data loss if happens in critical perl applications.

perhaps it worth to backport the fix?

Currently problem reproducable on Ubuntu 12.04 with lates updates.
