Regression 16 bit threading problem with Use explorer to handle desktop window commit

[paul]

If I start two 16 bit programs in wcmd or in the original case use 
wintask to start a Delphi 1 based GUI the second program does not get a 
new thread detach.
As soon as the switch occurs back to the original task a page fault occurs.
See bug for traces, more details and sample program.
