cache_bootstrap was not cleared

I have similar issue with APC 7.x-1.0-beta4.

When enabling/disabling a module, record 'system_list' should be deleted from the table by function call system_list_reset(). However, when I enable/disable a module, table {cache_bootstrap} won't be cleared as expected (as least record 'system_list' is not cleared from table {cache_bootstrap}).

This happens when module APC (7.x-1.0-beta4) is enabled. After having it disabled and having my settings.php file updated (to remove APC related code), everything looks fine again.

Also clearing the cache fails! When I clear the cache, no error is shown. However I have some pages which take a long time to load when not in the cache. When I click clear cache, they are fast as ever. Restarting apache fixes the problem (obvously apc is also cleared on a restart of apache)

Also I don't know if this is related, but I think since beta 4, one of my ajax blocks no longer works after a while.

Hmm strange, since the apache restart, clearing the cache also seems to work again at this moment.
