Hmm. So under what conditions should it continue, and under what

EINTR indicates a temporary failure. In that case it should always retry.
A common macro
Armin Ronacher armin.ronac...@active-4.com added the comment:
The following minimal C code shows how EINTR can be handled:

main()

char buffer[BUFFER_SIZE];

Armin Ronacher armin.ronac...@active-4.com added the comment:
Wouldn't retrying on EINTR cause havoc when you try to interrupt a process?
All your C applications are doing it, why should Python cause havok there?
Check the POSIX specification on that if you don't trust me.
That is: what
Armin Ronacher armin.ronac...@active-4.com added the comment:
There is a funny story related to that though :)
BSD avoids EINTR entirely and provides a more convenient approach:
to restart the interrupted primitive, instead of making it fail.
BSD does, but the Mach/XNU kernel combo on OS X
