As long as you allocate memory from a pool, it's not required to
free the memory explicitly via ngx_pfree(). Memory will be
freed automatically on the pool destruction. Moreover, in most
cases ngx_pfree() will not be able to do anything as it can only
free large blocks of memory.
The ngx_pfree() function is only useable in some special cases
when you have to free large blocks of memory before the pool will
be destroyed. For example, nginx uses ngx_pfree() to free
connection's buffer memory for idle keepalive connections, see
