[Gnumed-devel] Error with threading.Lock.acquire ()

[Ian Haywood]

This one's got me stumped:

[PANIC]

The problem is using Lock.acquire (blocking = 1), changing to Lock.acquire () 
or Lock.acquire (1) fixes it. The problem is, "blocking = 1"
is acceptable according to the docs (and the source of threading.py!)
 
My version of python is 2.2.3-2.1 (Debian unstable)
