There are two ways to do this. One is to completely flush the cache each time,
and reload it from scratch. The other is to search the cache for exiting rows
to update/add/remove.

The first is fairly simple. use CONTAINER_FOR_EACH to go through and free each
row, then CONTAINER_CLEAR, followed by inserting all rows again.

The second is a little more complicated, but required if you want to keep some
non-cache data in the row. For an example, see the ifTable cache_load in
mibgroup/if-mib/ifTable/ifTable_data_access.c.

yep, that would work.

Since the agent is single threaded, and alarms don't run while requests are
being processed, it shouldn't be an issue.

You are lost in a twisty maze of little standards, all different.
