/**

|
Lock-free FIFO memory allocator.
|
|
|
|
This allocator is suitable for use with CallQueue and Listeners. It is
|
|
expected that over time, deallocations will occur in roughly the same order
|
|
as allocations.
|
|
|
|
@note This version of the fifo free store uses less memory and doesn't require
|
|
thread specific storage. However, it runs slower. The performance
|
|
differences are negligible for desktop class applications.
|
|
|
|
@invariant allocate() and deallocate() are fully concurrent.
|
|
|
|
@invariant The ABA problem is handled automatically.
