I don't understand what the problem is, here. I mmap more than 128MB
at a time with some regularity; no problems to report.
Perhaps the author of the comment you enclosed didn't check that his
resource limits were set appropriately? I note that:
1) The default "datasize" limit is 128MB
2) Many other Unix variants incorrecly *don't count mmap allocations
against *any* resource limit *at all**, allowing the use of mmap()
to completely bollix up the system.
