Nice theory, but:

1) Windows 95/98/ME are not 'modern operating system'
2) Even on windows NT/2000 it is enough to dump special text file to
screen to kill entire system as normal user
3) Even on more 'reliable' systems, you have to configure them quite
specially to avoid bad behavior in
critical situations.

Memory - if application has unlimited memory quota, it can reduce system
to crawl or even crash it. Fortunately java has it embedded in jvm, but
browser does not (and if there is some bug in jvm or browser it can
happen). Same goes for threads spinning cpu - with enough processes you
can have problems with recovering computer in timely manner.

In fact, there are tricks that could burn your processor from inside
program :) (I don't know if it is still a case, but it was in <486 days).

In short - modern OSes are protected from some, or even most crashes (a
lot of improvement till old MS-DOS/win3.1 times). But unless you want to
buy mainframe with 'real' OS, you can forget about 100% robustness.
