Hi Tim,
as PD is largely not thread-safe, you can only do that if it doesn't 
interfere with the operation of PD.
e.g. a patch may be accessing the buffer as well etc.
I'm afraid it's not easy (if possible at all) to introduce thread-locks 
for the PD buffer stuff.
(vasp uses it's own "immediate" dynamic buffers for that and other 

best greetings,
