Comment:

 Hi,
 I am experiencing the exact same problem, with latest version from SVN.
 The while loop referred to by the OP is in
 ''simple_segregated_storage::find_prev'', which is called from
 ''ordered_free''. There is a comment there that this is a slow function.
 My app allocates around 70MB, through ''fast_pool_allocator'' based maps,
 as well as pool_allocator based strings/vectors.
 Application shutdown takes ~10 minutes. The problem disappears if I stop
 using ''pool_allocator'' in strings & vectors (''fast_pool_allocator''
 does not cause any issues).
 I'll try and attach some code to reproduce the problem tomorrow.
 Thanks
