 The goal of this is exactly what is stated - improve performance.
fork() is extremely slow operation on Cygwin because of Windows'
nature. Make already had all the code so it took quite a short time to
adapt it.
 I know that gcc toolchain also uses this for speedup.
 There was a short discussion in Cygwin ML with test results, sorry, i
cannot find the URL, Google fails to find it.

Kind regards, Pavel Fedin
