[Vm-dev] UUID new crashes 64bit vm

[John M McIntosh]

Yes, well however I'd suggest one peers at that smalltalk code and  
adjust things to pull a chunk of bits from /dev/urandom in a single read
and mask off the number of bits needed, versus the loop that is there  
making bits. This would be safer and likely faster since the fallback  
code
is based on squeak smalltalk based random number generator which  has  
numerous cryptographic flaws and there exists a probability that
UUID generated from the existing code *could* repeat given just the  
right circumstances.
