Milestone:  To Be Determined              |   Component:  interprocess
  Version:  Boost 1.48.0                  |    Severity:  Regression  
 Keywords:  shared_memory deleting files  |  
------------------------------------------+---------------------------------
 This is reproducible on OSX.

 In boost 1.48.0, shared_memory creates a folder in /tmp/ called
 boost_interprocess/ all shared memory files are put in that folder.

 In boost 1.47.0 and prior, shared_memory creates a folder in /tmp/ called
 boost_interprocess/
 and in there, it would create another sub-directory named by the boottime.
 It would also delete any other folders/files located in
 /tmp/boost_interprocess

 The problem is, now that I am using boost 1.48, my application uses
 /tmp/boost_interprocess.
 If any program using boost 1.47.0 shared memory, it will delete every
 files and folder in /tmp/boost_interprocess (which is what boost 1.48
 uses.)

 I surely have the access to all my programs, and can make sure we are all
 using boost 1.48+, but I can't guarantee that the user doesn't have a
 program using boost 1.47 or prior...

 To fix this, there's one easy way, change the folder name
 boost_interprocess to something else... boost_interprocess2 for example.
 Hence, boost 1.47 will only delete what's in /tmp/boost_interprocess and
 leave all the other programs using /tmp/boost_interprocess2 in peace...

 or you could give the option to the users to change that folder name.
