Re: Dale's note on even more stack being required for a task using the 68881 .. right, I realized that might happen, so the LWP stuff now has a global variable which holds the amount of extra stack needed (defaulting to 96+8[+3 for LW align] bytes. Any program which uses or might use the 68881 can up the value. The idea is to NOT have to hard program the ForkLWP() calls dependant on what EXEC does with a poor task's stack. BTW, if you get a stack overflow due to EXEC in a task switch, which screws up memory below the allocated stack, it usually crashes the machine so thouroughly that my poor A1000 asks for KickStart on reboot! -Matt
