[Mono-list] How to use the Boehm garbage collector

[HannibAl Bundie]

Thanks for your answer.

So, theoretically, I do nothing and I can benefit from an effective 
collector ?
Nevertheless, I would like to force a garbage collection. In this case, what 
namespace I have to use in the aim to apply a GC_gcollect() ?

Thanks and sorry this probably stupid question
