[Vm-dev] Unix heartbeat thread vs itimer

[Levente Uzonyi]

IMO the best solution would be to add command line parameters to set the 
priorities - both main and heartbeat using relative values, and keep the 
current behavior if none was given. Ben's example would be 0 for both 
parameters.
Then the error message on startup could just say to set one of the 
parameters to run the VM (e.g. 0,0 or -1,0, etc).
AFAIK you can always decrease the priority of the threads on linux, so 0 
and negative values should always work.
