not able to download. getting timed out.
anyway, I tried compiling the old code and it failed. TMemoryManager
seems to have changed a bit. Adjusted the code to match the cmem
example given in the manual and I got errors saying that InitThread ,
DoneThread and RelocateHeap are undefined fields in TMemoryManager.
Compiled fine when those three lines were commented out.
It did not crash on Linux! and it seems to collect as well!! (using
libgc 6.6 that comes with opensuse 11.1)
I love deadlines. I like the whooshing sound
they make as they fly by.
