Oddly, I was confused about the line because it was on its own line.
I thought it was just:

"while (al==NULL);"

equivalent to:
  while (al==NULL) {};

  Which I thought was strange.  On my dual-CPU 2.0.36 Linux machine,
this endless loop couldn't be stopped with a kill, kill -15, kill -9.
But oddly, the hung program would halt immediately when I reniced it.
SMP linux can be weird sometimes.

  The problem arose because I had needed to call init_readables and
init_artifacts in the standalone random map generator.  (The server
has all these data structures around.)

  But endlessly looping isn't optimal behavior....
