It seems that it does now. In smallAlloc() and bigAlloc(), if 
allocation fails it collects garbage and then:
    if (lowMem) minimize();
On Windows, lowMem is calculated with GlobalMemoryStatus(), and 
is true if "Less than 5 % of virtual address space available"

This is hardly ideal, but better than nothing I guess.
