The Trunk: Network-ul.176.mcz

Levente Uzonyi uploaded a new version of Network to project The Trunk:
http://source.squeak.org/trunk/Network-ul.176.mcz

==================== Summary ====================

Name: Network-ul.176
Author: ul
Time: 2 April 2016, 9:06:31.957661 pm
UUID: 1b580a49-2663-4d5d-a659-606ba1c698de
Ancestors: Network-ul.175

Use primitiveMakeUUID when it's available in UUID >> #makeUUID. This should keep things snappier when UUIDPlugin works, and it should decrease the possibility of a UUID collision due to our poor seed generation in Random.

I thought the non-primitive version was snappy enough already?

Hi Tobias,

It is snappy enough, but it's not such a good idea to rely on
UUIDGenerator while the seeding problem exists in Random[1].
I have a solution for that in progress, which works without VM support,
but it still has a few question marks.
When I asked for a primitive to solve that issue, the thread[1] got
totally derailed.
Btw, this change should have no effect when UUIDPlugin doesn't work.
