 In http://git.openmoko.org/?p=om-locations.git;a=blob;f=tools/om-
 locations-map-pack.c;h=4fefe1181db9450b64ce48c6a9d23b7242d73ca3;hb=HEAD

 function fetch_sched() may call fetch_completion() (in line 351), while
 function fetch_completion() may call fetch_sched() (in line 312).

 This leads to infinite recursion if the "circumstances" are right.

 One of these circumstances is if om-locations-map-pack is run over a
 sufficiently large cache directory (with more than 2000 tiles).

 Thus, this bug prevents incremental downloading of reasonably sized tile
 sets (e.g. a tile set of a larger city).
