You can control the GC via the 'std.gc' import, which exposes the 'std.gc.disable()' and 
'std.gc.enable()' functions for turning automatic collection off/on, and the 
'std.gc.fullCollect()' function for manually initiating a collection run.

See: http://digitalmars.com/d/phobos/std_gc.html

As far as I know, in the case of cross-language DLL's (I assume the program you're writing 
the plugin for is not in D itself), the GC will only pause the DLL's own threads, but I 
could be wrong.
