Removed .wine and reran, but now it doesn't hang.
The new trace diverges from the old one right before the problem;
in the good log, there is no ProviderOrder key.
In either log, wininet.dll's startup loads mpr.dll. and mpr.dll's startup
checks for ProviderOrder in function wnetInit().

It turns out Installing Lotus Notes 7 trial sets the ProviderOrder key,
and then even running the wininet tests locks up.  Here's the last bit of
WINEDEBUG=+all ~/wine-git/wine tests/wininet_test.exe.so :

0009:trace:reg:NtQueryValueKey (0x38,L"ProviderOrder",2,0x33f550,30)
...
0009:trace:mpr:wnetInit provider order is L",npnotes"

Now to find the loop...
