temper, temper

pls read my reply to alan carefully .

Doing own malloc(), free(), m[un]map(), is a possibility we've
considered. Since we've got our own lib linked with the app, we probably
wouldn't even need LD_PRELOAD. our main issue is that not everything is
gcc/g77.

Of all the approaches the syscall traps was the least intrusive and most
portable of all, belive it or not.

BTW: this is all technical issues.
