I see the same problem here, ktrace says (kdump -T + script to create  
incremental timestamps):

2178 python 0.420467 CALL  
load_shared_file(0x93a20420,0x218000,0xe2614,0xbfffd350,0x4,0xbfffd2e0,0 
xbfffd354)
2178 python 0.420592 NAMI "/usr/lib/libcrypto.0.9.dylib"
2178 python 0.420825 RET load_shared_file 0
2178 python 0.421384 CALL close(0x5)
2178 python 0.42152 RET close 0
2178 python 6.57782 CALL open(0x430b0,0,0)
2178 python 6.57802 NAMI  
"/System/Library/Frameworks/Carbon.framework/Versions/Current/ 
Frameworks/HIToolbox.framework/HIToolbox"
2178 python 6.57818 RET open 5

The process is doing no systems calls for about 6 seconds between  
loading libcrypto and the HIToolbox.

I hope this helps a little,
