The number of seconds a user cache entry is allowed to idle in a slot in
case this cache entry slot is needed by another entry. Leaving this at

On busy servers when you first start up the server, or when many files
are modified, you can end up with all your processes trying to compile
and cache the same files. With write_lock enabled, only one process at a
time will try to compile an uncached script while the other processes
will run uncached instead of sitting around waiting on a lock.

RFC1867 File Upload Progress hook handler is only available if you
compiled APC against PHP 5.2.0 or later. When enabled, any file uploads
which includes a field called <literal>APC_UPLOAD_PROGRESS</literal>
before the file field in an upload form will cause APC to automatically
create an upload_<emphasis>key</emphasis> user cache entry where
<emphasis>key</emphasis> is the value of the
<literal>APC_UPLOAD_PROGRESS</literal> form entry.
</para>
<para>
Note that the file upload tracking is not threadsafe at this point, so
new uploads that happen while a previous one is still going will disable
the tracking for the previous.
