+ added support for thread local memory allocators by using MSPACE
mechanism in DLALLOC.
It can be enabled by compiling Harbour with HB_FM_DLMT_ALLOC macro.
By default up to 16 (HB_MSPACE_COUNT macro) independent memory
allocators is dynamically created for new threads. When more threads
is used then allocators are shared between them and HVM tries to
balance used allocators to reduce number of threads using the
same allocator.
It should give noticeable scalability improvement in some OS-es
where default memory manages has pure MT performance.
Please try to compiler speedtst.prg with Harbour compiled with
and without HB_FM_DLMT_ALLOC and compare results in this test:
speedtst --thread=2 --scale
using real multiCPU machine.
