If the filesystem calls are stupid then we should try to avoid them. Are there trac tickets for this? Can you give examples? Are these filesystem calls perhaps for source code inspection? My guess is that part of the problem comes from cached methods. Namely, when the @cached_method decorator is applied, it is tested whether the to-be-wrapped method has just the argument "self" or has further arguments; if there are no further arguments, some optimisations take place. But the problem is: For detecting the number of arguments, one often enough needs to inspect the source code! See sage.misc.sageinspect.sage_getargspec. Anyway. I'll try to see whether I can modify the code in sage.misc.cachefunc so that source code inspection is avoided.
