[zeromq-dev] weird bug

Hi Pieter,

The real issue with it for me, is that as a binding user (and high
abstraction-level programmer), the error is rather confusing. Especially
since it will mainly work fine, until there is some thread usage, whereupon
the code will stop working intermittently. A less persistent (or time poor)
person may just hold back on upgrading or drop the library altogether.

This seems like a great place for a socket option, HANDLE_EINTR or
something, and have handling the signal be the default, since almost always
it is what people would want, IMHO. Indeed, this was originally the case,
and was changed with only a little announcement. I feel most users
(extrapolating from me :P) wouldn't even have understood the ramifications
of the change from the email thread when it was discussed.
