Summary: XQ: global variables in embedded pf not resetted

Initial Comment:
I now file a bug report based on Jan Flokstra report on problems with memory 
allocation (see: 
http://sourceforge.net/mailarchive/forum.php?thread_id=31561760&forum_id=39803)

His problem (and also mine) is that mem_realloc is called with a NULL pointer. 
(The wrong handling of this NULL pointer should be another bug report.)

This realloc is called by PFarray_at() and PFarray_at() itself is called with a 
PFarray that contains only garbage. The reason for this PFarray to contain only 
garbage is that it is initialized only if the variable that stores the 
reference is set to NULL. This is however not the case when pf is called a 
second time without stopping (e.g. using MapiClient) as the variable itself is 
initialized globally to NULL.

While a fix seems rather easy I opened a bug report instead as this might be 
not the only place where global variables are initialized globally.

Perhaps Peters suggestion to run pf in a separate thread might be a good 
alternative to avoid such problems and to keep Mserver alive even if pf crashes.
