We are pleased to announce Combinatorrent v0.3.0
Combinatorrent is a bittorrent client, written in Haskell and with an emphasis
on concurrency.
This version has the following changes from v0.2.0:
- Numerous space leak fixes. The client doesn't leak memory anymore
for typical runs.
- A number

I am asking if anyone has seen the following behaviour from GHC under
