RFR: 8332551: Test vmTestbase/nsk/monitoring/MemoryNotificationInfo/from/from001/TestDescription.java timed out [v2]

[Kevin Walls]

> Short version:
> Stop testing this test with -Xcomp by adding requires vm.compMode != "Xcomp"
> 
> Make additional typo fixes and tidyups while here, it's just shocking.
> 
> TestDescription.java contains the test definition, so the "requires" goes there, with a comment.
> 
> Updates to from001.java are typos and clarifications, and a changed loop with a poll on a queue rather than block forever.
