In particular the "bytes allocated" have been close to the upper limit for
some time on my linux boxes.

T1969 stats from a HEAD built yesterday afternoon:
[("bytes allocated", "537023352")
,("num_GCs", "953")
,("average_bytes_used", "5471552")
,("max_bytes_used", "10244776")
,("num_byte_usage_samples", "9")
,("peak_megabytes_allocated", "28")

,("mutator_wall_seconds", "0.84")
,("GC_cpu_seconds", "0.25")
,("GC_wall_seconds", "0.25")
]
So bytes allocated was rather close to the limit and is still closer to the
new upper limit than the lower.

T4801 stats:
[("bytes allocated", "723868224")
,("num_GCs", "1299")
,("average_bytes_used", "10334167")
,("max_bytes_used", "21496744")
,("num_byte_usage_samples", "12")
,("peak_megabytes_allocated", "61")
,("init_cpu_seconds", "0.00")
,("init_wall_seconds", "0.00")
,("mutator_cpu_seconds", "0.45")
,("mutator_wall_seconds", "0.67")
,("GC_cpu_seconds", "0.51")
,("GC_wall_seconds", "0.51")
]
bytes allocated again close to the (old) upper limit, but
peak_megabytes_allocated was comfortably within the old range.
