Description

Spider processes that are launched from appion are are expanding to take up all of the processors on the node from which they are launched. This is problematic for two reasons. First, it takes up all the processing capabilities, and second it actually slows spider down significantly when the process it is working on isn't very parallelizable. The two places I've noticed this behavior are 1) when it is filtering an image during picking and 2) when doing an alignment of particles to a template. The behavior is the same for both spider 15 and 19.
