shared mutex should be recursive

[mur@…]

shared mutex should be recursive or such a mutex/lock should be added.

[Anthony Williams]

I consider recursive mutexes in general as undesirable. A recursive shared mutex would be particularly complex, and usage likely error prone due to the interaction between readers and writers. I have no intention of providing such an implementation.

whyyyyyyyyyy shit so I'm used to do it by my own

Such arrogance !! as if because you think one way the rest of the community can only be wrong. What about lock elevation and its reverse ? even windows natively implements an efficient recursive elevateable read/write lock ... but I guess it too complicated for boost developers so we should all do the work ourselves. Much less use is a timed mutex perhaps if that "complication" was removed it would be less "complex" to implement a useful semantic ?

Yes ... people ... roll your own don't wait as even in C++!4 there isn't one.
