Investigate MONO_GC_PARAMS

[Therzok]

Maybe it would be useful to turn on precise scanning to prevent false positive stack leaks?

excerpt from man:

              stack-mark=mark-mode
                     Specifies how application threads should be scanned.  Options  are  `precise`
                     and  `conservative`.  Precise marking allow the collector to know what values
                     on stack are references and what are not.  Conservative marking  threats  all
                     values  as  potentially  references and leave them untouched. Precise marking
                     reduces floating garbage and can speed up nursery collection  and  allocation
                     rate,  it  has  the downside of requiring a significant extra memory per com-
                     piled method. The right option, unfortunately, requires experimentation.

Precise was never supported on macos.
