<hr/><a name="_details"></a><h2>Detailed Description</h2>
<p>APR memory allocation. </p>
<p>Resource allocation routines...</p>
<p>designed so that we don't have to keep track of EVERYTHING so that it can be explicitly freed later (a fundamentally unsound strategy --- particularly in the presence of die()).</p>
<p>Instead, we maintain pools, and allocate items (both memory and I/O handlers) from the pools --- currently there are two, one for per-transaction info, and one for config info. When a transaction is over, we can delete everything in the per-transaction apr_pool_t without fear, and without thinking too hard about it either.</p>
<p>Note that most operations on pools are not thread-safe: a single pool should only be accessed by a single thread at any given time. The one exception to this rule is creating a subpool of a given pool: one or more threads can safely create subpools at the same time that another thread accesses the parent pool. </p>
