I have had similar problems (not gdb, but other things that read
/dev/random), especially on domUs. I run 'du / > /dev/null' and that
generates enough disk interrupts to get randomness.
Perhaps we need randomd(8) that watches the entropy level and when too
low reads files from the filesystem to bring it back.
