/* CV 2012-05-21: Moved printing heap size here from strace::activate.
The value printed in strace.activate was always wrong, because at the
time it's called, cygheap points to cygheap_dummy. Above all, the heap
size has not been evaluated yet, except in a forked child. Since
heap_init is called early, the heap size is printed pretty much at the
start of the strace output, so there isn't anything lost. */
