I ran this test on a machine with 224 logical CPUs and it fails with:
ITERATION 3
test TestHandshake.testHandshake("SegmentMismatchAccessor",
TestHandshake$$Lambda$57/0x00000001000e7968@37c4b344): failure
java.lang.OutOfMemoryError: Cannot reserve 1000000 bytes of direct buffer
memory (allocated: 536008192, limit: 536870912)
SegmentMismatchAccessor allocates a 1MB native segment for each CPU on
each iteration. This can quickly reach the allocation limit if there is
no intervening GC. Explicitly close the segment after each iteration to
release the memory.
