Back in '86 we incrporated 'realloc'-like functionality into the generic V.2-286 (for multibus 1 Intel 310's) and improved performance on out 1Mb RAM machines for ld jobs by up to 40%! (operations like rebuilding kernels, etc.) I guess uPort assumes all AT's have lots of core . . . Eric Dorman siolmd!eric at sdsioa
