[dart-misc] Dart VM on server & observatory

[Adam Lofts]

Hi,

I am running a server on the dart vm and am having some issues with memory
usage. The dart observatory should be useful in helping me figure out what
is going on. Is it OK to run the observatory in production or does it do
bad things e.g. slow down the vm, keep object references alive.

For example when you pass --observe to the vm it will automatically set
pause_isolates_on_exit. Presumably this means the objects referenced by the
isolate cannot be collected until someone unpauses the isolate. Are there
any more issues like this?

Thanks
Adam
