Thread Profiling

[JamesHoward]

Are there any good thread profilers available that can profile a
thread as it is running instead of after execution is completed?

I would like to find a python class which looks at a currently running
thread and if its memory exceeds a certain amount than kill it.
Ideally I would like the program to track memory used not just by that
thread, but by any threads or processes that it may spawn.

If there isn't anything like that, then something that lets me set the
maximum memory allowed to be allocated within a thread would be
acceptable also.

Thanks in advance,
James Howard

Killing a non-cooperative thread is undefined behavior. You can't do
it with the Python threading API and even OS thread implementations
that permit it don't guarantee that your process will be in a sane
state afterward.

thread, but by any threads or processes that it may spawn.

Memory isn't allocated on a per-thread basis and there's not really
any way to know what should be charged to a particular thread. That's
on top of the normal caveats about trying to judge memory usage within
