Description of problem:
The daily cron job /etc/cron.daily/slocate.cron does not release memory.
Version-Release number of selected component (if applicable):
Secure Locate 2.7 - Released January 24, 2003
Memory usage jumps every time the cron job runs, either by the cron job or manually.
Steps to Reproduce:
1. Let the cron job run.
Memory utilization does not drop down after the cron job is done.
The memory utilization should drop,

System monitor output when the /etc/cron.daily/slocate.cron is executed manually.
Running slocate allocates many entries in the dentry and inode caches,
which are accounted for in the Slab: line of /proc/meminfo.
libgtop2's glibtop_get_mem_s () computes "user" memory as
MemTotal: - MemFree: - Cached: - Buffer:
(using the /proc/meminfo terminology), which means that the dentry cache
is accounted for as "user" memory.
I'm not quite sure whether just subtracting Slab: from "user" memory is
good enough (some of the memory allocated as Slab: is directly caused
by user-space actions, e.g. opening a file, creating a process), but
I think it still would be an improvement. More detail is available in
/proc/slabinfo if necesary.
