The caches for expressions can potentially consume a lot of resources #11

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Numexpr aggressively tries to cache parsed expressions in dictionaries so
as to minimize the overhead of parsing them.  However, doing this in
scenarios where a *lot* of different expressions are computed can lead to
very large dictionaries which consumes a lot of memory and CPU.  This
should be fixed.
