Comment (by eschnett):

 More notes:

 It is not a memory leak; only libc's free memory increases.

 The memory increases in jumps of a few MByte. These jumps occur near mode
 switches or near synchronization.

 The problem only occurs with Intel, not with gcc. With Intel, the libc
 free memory increases linearly, up to 1.4 GByte in one particular test
 case. With gcc, the libc free memory stays bounded at about 29 MByte.

 It is not due to RotatingSymmetry180. It is not due to the routine
 SyncGroups. It is not due to Carpet's timers.
