[phobos] phobos commit, revision 2319

[Jonathan M Davis]

Well, the Phobos unittest build continues to fail by running out of memory. I'm 
really quite stumped by it. Running it in Linux, I don't think that it ever goes 
much above 100MB, and most of the time, its memory consumption is considerably 
less. However, on Windows, it goes above 900MB and decides that its run out of 
memory.

The problem does appear to be in std.datetime, since if I comment out the 
module, it's fine. If I comment out a large portion of the unit tests, it's fine, 
but I get the impression that it's due to the large number of unit tests rather 
than any particular test. Maybe  it's due to the templated test functions I'm 
using taking up too much memory which isn't released? There _is_ at least one 
bug relating to memory not being released during CTFE.

However, to make matters even more interesting, when I ran the unittest build in 
wine, it didn't have any memory problems. I think that it might have hit around 
300MB, which is more than the Linux build got to, but it certainly wasn't in 
excess of 900MB. So, I'm rather stumped as to what to do about it.
