Konstantin Belousov 19e008e7f7 crt_malloc: Be more persistent when handling mmap() failure 
In the situation with limited address space, together with
fragmentation, it is possible for mmap() request in morecore() to fail
when asking for required size + NPOOLPAGES, but succeed without the
addend.  Retry allocation there.
