21. brk() and mmap() doesn't report out-of-memory through its return
value. Instead, page-fault reports the error.
22. anonymous mmap pre-maps requested number of pages when contiguous
pages are available. Demand paging is used when not available.
22. Anonymous mmap pre-maps requested number of pages when contiguous
pages are available. Demand paging is used when not available.
23. Mixing page sizes in anonymous shared mapping is not allowed. mmap
creates vm_range with one page size. And munmap or mremap that
needs the reduced page size changes the sizes of all the pages of
the vm_range.
24. ihk_os_getperfevent() could time-out when invoked from Fujitsu TCS
(job-scheduler).
