well,i can't say for sure but i'll present you an example. psycopg was
built with multithreading in mind: every time it take a possible long
operation that does not alter the internal state of the python
interpreter it releases the global lock. every function was written
around this concept. how much code will be reusable in other projects?
how much difficult would be to merge? also, psycopg has a very
sophisticated postgresql->python type casting mechanism and will be much
less usefull to a lot of people without it.

imo, the only possible merge is when one of the projects gets
discontinued and the authors "merge" into another project. this is true
not only for those projects but for every project that get started
because the author feels others are pushing in the wrong direction..=20
