Comment (by igaztanaga):

 BOOST_INTERPROCESS_FILESYSTEM_BASED_POSIX_SHARED_MEMORY changes the way
 shared memory name is created from a user defined name. If true, the name
 is based on a temporary file. I don't know why this file-based name works
 and the classic one (/shm_name) fails.

 If we want to maintain binary interface, we will need to check for the
 jailed environment in runtime and change shm name behaviour in runtime.

 I'd need a bit of help to know how a process can check if it's working in
 a jailed environment using freebsd C api. Maybe sysctl (2)?
