Hi,

I'm getting reports that my program sometimes stutter a little bit, and
that turning off the garbage collector fixes it.

So I thought I should try to minimize the root set by avoiding to load
the data segments of dynamically loaded libraries, since I know
that there are no root pointers there.

In gc.h, the most straight forward way seems to be calling
'GC_set_no_dls()',
But the documentation for it says:

  "In some environments like Microsoft Windows

   and Apple's Darwin, this may also prevent
   registration of the main data segment as part
   of the root set"

This sounds a bit scary. Is this correct?

Perhaps it's better to implement the 'GC_has_static_roots_func'
callback, and always let it return 0?

Thanks for any help.
