I've seen something that may be the same running cygwin 1.1.4 on both WinNT 4 and Win98.  If I start an 
external program and fork it from the shell, i.e:
   gvim.exe &

, and then exit gvim, bash eats up the CPU until I hit return at the prompt to allow the 
    "[1]+  Done        gvim"
message to print.  After the message is shown, things seem to run ok, but bash does eat up the CPU
until the message prints.o
