Subject: [boost] [interprocess] maximum length for names of mutexes, memory segments etc.

A component of Boost.Flyweight called intermodule_holder internally
uses some Boost.Interprocess objects with very long names intended
to guarantee sistem-wide uniqueness. For instance, this is how such
an internal mutex can be named (87 chars):
Alas seems like 87 chars is too much in some platforms like NetBSD:
terminate called after throwing an instance of 'boost::interprocess::interprocess_exception'
what(): File name too long
See http://tinyurl.com/6m693p . This problem also shows in some of
Boost.Inteprocess own tests for NetBSD.
Is there any maximum length we can safely commit to across allplatforms?
(docs are silent wrt this).
