Description

While trying to reproduce bug #5652 (using the suspend/resume cycle) I noticed some memory leaks in the fctl module:

streams_dblk_80 leak: 1 buffer, 192 bytes
            ADDR          BUFADDR        TIMESTAMP           THREAD

I'm not sure the suspend/resume cycle is relly related to this bug.

This is a duplicate of #5512. We do see a different stack trace just because the ecpp(7d) module was unloaded and some other victim was loaded on the same addresses.
