I'll add a report that I'm still seeing this behavior with OS 10.4.6 on a Macbook Pro 15" with beta 6 of PW, connecting to the Mac from an XP Pro client with PW not even running.
Smbd processes spawn out of control and require a killall to recover. The problem appears to be alleviated by disabling the virtual ethernet adaptor and the Parallels Host-Guest adapter.
Also, repeated errors included below appear in the nmbd and smbd logs when the virtual network ports are enabled:
Code:

standard input is not a socket, assuming -D option
[2006/05/09 22:46:33, 0] /SourceCache/samba/samba-92.15/samba/source/lib/util_sock.c:open_socket_in(724)
bind failed on port 137 socket_addr = 0.0.0.0.
Error = Address already in use
Also, I find that network browsing for Windows clients in the host OS is unreliable when the virtual network ports are enabled in the Mac's Network configuration. Often, no servers appear.
