[Openmcl-devel] mach ports leaking?

When running a CPU+memory intensive job, I notice that the number of  
mach ports is fairly high for the ccl process - and it is increasing  
rapidly:

   PID COMMAND      %CPU   TIME   #TH #PRTS #MREGS RPRVT  RSHRD   
RSIZE  VSIZE
30223 mdworker     0.0%  0:00.18   3    50     31  664K  2712K   
2428K    34M
30214 bash         0.0%  0:00.01   1    14     18  228K   660K    
896K    18M
30213 login        0.0%  0:00.02   1    17     55  284K   260K   
1064K    19M
30211 dx86cl64    71.4%  3:45.21   3 92673+   327  226M+  188K   228M 
+  256M


Is this a possible memory/thread leak?
As little as I understand about the implementation, I doubt it's on  
the heap: (ccl:gc) doesn't change #PRTS.

I'm on Darwin64 (OSX 10.5.6), with CCL 1.2 and also current checkout.
