I have also seen such a behaviour (although not recently), as well as a variant which may help to shed some light on the whole issue.
In the variant behaviour, I attempt to suspend aptitude while it runs another process, while installing packages. This appears to freeze aptitude, but a look at the processes shows that aptitude is perfectly fine, but the subprocesses it has forked are stopped (ps report "T" state). In this situation, sending a SIGCONT to those stopped processes allows them to proceed - but still no way to suspend the whole. I observed this with various subprocesses - apt-listbugs and package postinst scripts. After the requested installs are finished, Ctrl-Z is functional again. Another factor that may be worth noting, is that my aptitude process is always run from within a screen(1) session. I'll try to think of launching one outside of it and check how it works. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
