> When Axis2/C is used with the httpd module to allocate memory in apache global pools
one need to call the axutil function axutil_allocator_switch_to_global_pool. To switch back
again to use apache local pool(request level allocation) one need to call the axutil_allocator_swith_to_local_pool.
> However there could be problematic situations if used this carelessly. For example consider
the following scenario.
> swith_to_global
> ...do something...
> switch_to_global
> ...do something
> swith_to_local
> !!! Now am I using global memory or local memory?.  Ideally now I should still be using
global memory. But accoring to current Axis2/C implementation at this stage I'm using local
memory. This could lead to unavoidable problems.
> Attached patch fix this.
