Hi,
I am using Dynamic shared memory areas(DSA) to manage some variable
length shared memory, I've found that in some cases allocation fails even
though there are enough contiguous pages.
The steps to reproduce are as follows:
1. create a dsa area with a 1MB DSM segment
2. set its size limit to 1

The easiest way to fix this is to swap the order of step b and step c. On the
other hand,
let sigsetjmp clean up the queue may also be a good choice. What do you think?
Attached the patch, any feedback is greatly appreciated.
