Workaround: open a pipe to the shell before your process gets big:
FILE *fp, *popen();
.
.
if ((fp = popen("/bin/sh", "w")) == 0)
oops!
Then write commands to the shell like:
fprintf(fp, "%s\n", whatever...);
fflush(fp);
Don't forget fflush() or things will reach the shell much later than intended.
