Database size problems

[denistoikka]

I found strange behaviour of the database:

1. Database size is always growing, even if I delete some key/values pairs and then rewrite them with the same content.
   When I make "./bolt pages path/to/db" it returns hundreds thousands of free pages; looks like they are not being reused and their amount is only growing each time I put something to db.

2. Database is growing by ~1GB each time I make "./bolt get path/to/db bucketName key"

"./bolt stats path/to/db" gives next output:

Aggregate statistics for 2 buckets

Page count statistics
    Number of logical branch pages: 1
    Number of physical branch overflow pages: 0
    Number of logical leaf pages: 4
    Number of physical leaf overflow pages: 24412
Tree statistics
    Number of keys/value pairs: 10
    Number of levels in B+tree: 2
Page size utilization
    Bytes allocated for physical branch pages: 4096
    Bytes actually used for branch data: 84 (2%)
    Bytes allocated for physical leaf pages: 100007936
    Bytes actually used for leaf data: 100000235 (99%)
Bucket statistics
    Total number of buckets: 2
    Total number on inlined buckets: 1 (50%)
    Bytes used for inlined buckets: 16 (0%)

In the meantime, real size of the database is 37GB.

Operation system is OS X Yosemite, Go version 1.3.3

Can you please assist me, maybe I'm doing something wrong?

Looks like fixed here #304

It looks like a regression got into Bolt for databases larger than 2GB from a few commits before. Let me know if you have any other issues. Thanks for reporting!
