multiprocessing callbacks?

Dangerous behavior of list(generator)
In most cases, `list(generator)` works as expected. Thus, `list(<generator expression>)` is generally equivalent to `[<generator expression>]`. Here's a minimal case where this equivalence breaks, causing a serious and hard-to-detect bug in a program: def sit(): raise StopIteration() ... [f() f... 2 Jan 2010 16:05
