examine memory in background?

[Johan Claesson]

When attaching to a process with gdb the process freeze its execution
and waits for gdb execution control commands. What if I want the
process to be running under the gdb session. I like to just examine
memory from gdb. Can I put the attached process to run in the background 
somehow? 
Any other approach applicable?

The problem is that if the process in question does not do certain
things regularly the system will restart.
