[plt-scheme] threads, memory leakage?

Dear All,

I'm running mzscheme 350.2 on my windows box.
I've got a threading Object Database Server (persistent
roos) running, listening on TCP 4001. I see memory usage
increase with each test run of my client program. I[m now
at client 62 (i.e. 62end thread) and memory usage has increased
from a little 22MB to 114MB now.

Are there any reports on memory leakage using TCP + threads
in mzscheme currently?

Thanks in advance for your answers,

--Hans
