To support pynodes we had to make Python thread-safe in Blender. Also, 
because pynodes were giving different results depending on the number of 
rendering threads and might even crash (race conditions), as a test I 
disabled the releasing of Python's global interpreter lock (GIL) by 
setting release time to max int in Blender.

That fixed pynodes related troubles and nobody reported problems with it 
(afaik), but you may have found a case where it breaks things. So please 
try this:

In Blender's Text Editor create a script with these two lines:

import sys
sys.setcheckinterval(100)

Run it (ALT+p) and then try your script(s). If they work fine you can 
add these two lines in your scripts as a workaround.

Please tell us if this fixes the problem.
