Well, you don't say how big huge is, so...Have you looked into IPC::Shareable? You can tie your hash to the shared memory region, and then just make sure you lock it appropriatly before reading/writing. I use this in multi process (not threads) programs and it works quite well for me.If the standard shared memory segment size is too small (32Mb?), you can increase it runtime by adjusting /proc/sys/kernel/shmmax or re-building the kernel
Cheers,
