[ https://svn.apache.org/r1558592 ]
QPID-5484 [linearstore] Poor performance relative to legacystore. Partial fix:
The use of /dev/random exhausts the kernel's supply of non-deterministic random
data, and calls to read from it block until enough is available. It has been
determined that /dev/urandom is good enough for this use-case (Journal serial
numbers), and does not suffer from blocking.

> The linearstore performance is poor compared to the legacystore. As
> linearstore has similar architecture to legacy store (except for file
> management), the performance ought to be comparable.
