My wish has to do with Grid and Threads packages:
1) Efficient usage of memory - Once a grid command finishes the memory allocated should return to Maple (I am not sure whether this is possible or not). There is a post in the list showing that, in some calculations using Grid, Maple hangs for no apparent reason.
2) A clear explanation in the help files (examples) on which variables should be Grid:-Set and which don't. (Although I have received help from tops users on the list and from maple support, the answers are not the same in some cases).
3) CodeTools:-ThreadSafetyCheck - Some of the functions that are threadsafe checked by this command causes Maple to hang. Is the list of threadsafe functions updated?
