+1: set "searching" local atomic struct to true
+2: for each thread:
+
+  if done=true; exit
+
+  if searing, division_syn, division_ack, undevidable: go to next
+    if all seem to be searching, set global done=true
+
+  if not: continue below

+3: record area_covered in own array, if more threads proceed to next, else continue below
+
+4: pick thread with largest area_covered:
+5: if division_syn or division_ack or searching or undevidable, go to next
+
+5: set division_syn to true, wait for division_ack
+6: divide(): copy over half of x/y, copy divisions, check and set undevidable, start to do work
+
+thread is working.
