Bug#628992: cupt: cannot be resumed with job control (unable to receive socket message length: Interrupted system call)

Package: cupt
Version: 2.1.0

Hi,

Typical amd64 experimental system. Today "cupt update" was taking a
long time, so I wanted to suspend it, put it in the background, and do
something else.

So I hit ^Z. Unfortunately a part of cupt seemed to continue running,
updating the download progress information:

| $ cupt update
| E: a syntax error: expected: semicolon (';') before 'Dir::Media::MountPath "/media/cdrom";
| '
| E: unable to parse config file '//etc/apt/apt.conf.d/00CDMountPoint'
| W: skipped configuration file '//etc/apt/apt.conf.d/00CDMountPoint'
| Get:1 http://mirrors.kernel.org/debian squeeze-proposed-updates Release
| Get:2 http://security.debian.org squeeze/updates Release
| Get:3 http://mirrors.kernel.org/debian squeeze Release
| ^Z0% [1 squeeze-proposed-updates Release 0B][3 squeeze Release 0B] | 0B/s | ETA: 0s
| [1]+ Stopped cupt update

| 100% [1 squeeze-proposed-updates Release 0B][3 squeeze Release 0B] | 0B/s | ETA: 0s

Then I ran "fg" to resume.

Probably there is a missing

if (errno == EINTR)
continue;

somewhere. Anyway, thought you might like to know.
