I seem to run into an issue where XFCE Terminal on slackware64-current will continue to allocate more memory as it continues to run.
I'm currently using the multilib packages from http://slackware.com/~alien/multilib/current/
on one machine and the base packages from slackware64-current on another. Both show this issue. If there's any troubleshooting I can do to help work this out I'd be happy to do so. I have double checked that I'm up to date before posting this.
Current workaround - use konsole instead
