[boost] Copyable mutex

Actually I don't want to copy a mutex.  I just want my class that has a
mutex to be copyable, without having to write a copy ctor and operator=
(that copy everything except the mutex).

Using this class solves the problem for me, but I have a feeling it is not
safe to do this.

class recursive_mutex_ignorecopy : public boost::recursive_mutex
{
public:
    recursive_mutex_ignorecopy() : boost::recursive_mutex() {}
    ~recursive_mutex_ignorecopy() {}
    recursive_mutex_ignorecopy(const recursive_mutex_ignorecopy&) {}
    recursive_mutex_ignorecopy& operator=(const recursive_mutex_ignorecopy&) {}

};

Is this a good solution that could maybe be made part of boost, in such a
way that it is guaranteed to work and be safe?

Or is there a better solution?

Thanks,
Phillip Hellewell

P.S.  Perhaps this is a moot point, sinceI just realized that for
thread-safety I really need to write my own copy ctor and operator= anyways,
that will be synchronized with my other functions that initialize shared
pointers and stuff.  And I need to lock the rhs's mutex too...
