Dear all,

I have come across another really strange bug in rpois.
If I do
> rpois(1, 1000000 * rpois(1, 10000))
sometimes it hangs, and hangs...
On my XP1000 alphaev6 workstation, it seems to happen more 
frequently than on other machines. I started a session on an older 
computer, and from the start, it looks like this:
> rpois(1, 1000000 * rpois(1, 10000))
[1] 1537190728
> ^[[A
Error: syntax error [whoops, I'm usually using ESS]
> rpois(1, 1000000 * rpois(1, 10000))
[1] 1507263999
> rpois(1000, 1000000 * rpois(1000, 10000))          
[hanged here, killed with ^C]

> rpois(1, 1000000 * rpois(1, 10000))
[1] 1463075843
> rpois(1, 1000000 * rpois(1, 10000))
[1] 1438068697
> rpois(1, 1000000 * rpois(1, 10000))
[hanging]

I think this is strange, because I've been doing this stuff 
a lot lately, but usually with a rather small parameter to the 
second rpois.
