In fact, it really is a C program, and sadly, it seems they really
implement it that way (by greping over the code for about 30 seconds);
See src/mygetline.c on hg tip[1]:
41 while(1) {
42 res = read(fd, &ch, 1);
Maybe coders need to be educated about how not to write code in order to
avoid (syscall-)bloat?
