[Newbies] Linux locks up when handling large data sets

[squeak414]

Hi, I've been testing Squeak's ability to handle large amounts of data. This
snippet:

testArrayFilling
        | startTime endTime iArray jArray kArray |
        iArray := Array ofSize: 100.
        1
                to: 100
                do: [:i |
                        jArray := Array ofSize: 1000.
                        1
                                to: 1000
                                do: [:j |
                                        startTime := Time millisecondClockValue.
                                        kArray := Array ofSize: 1000.
                                        1
                                                to: 1000
                                                do: [:k | kArray at: k put: 
Object new].
                                        jArray at: j put: kArray.
                                        endTime := Time millisecondClockValue.
                                        Transcript cr; show: i asString , ',' , 
j asString , ' ' , (endTime -
startTime) asFloat asString.
                                        startTime := Time 
millisecondClockValue].
                        iArray at: i put: jArray].
        Transcript cr; show: 'Finished'

creates about 5 million objects , then the image freezes. When I run on the same
machine under Windows, it happily continues until the short of memory warning (
about 70 Million objects in my case). The VM is 3.7 in both cases, the image
Damien's 3.9 development image.

There seem to be a number of Unix lockup issues. Is a later (or earlier) VM
likely to fix this please?

Thanks,   ...Stan
