Is the following problem a specific cygwin problem and how can I overcome it? It happened to me while trying to invoke haddock:

$ haddock -h hello.hs C:\haskell\cygwin\bin\sh.exe: *** fork: can't reserve memory for stack 0x40000 - 0x240000, Win32 error 487 4 [main] sh 1212 sync_with_child: child 988(0x72C) died before initialization with status code 0x1 8217 [main] sh 1212 sync_with_child: *** child state waiting for longjmp C:\haskell\cygwin\bin\sh.exe: *** fork: can't reserve memory for stack 0x40000 - 0x240000, Win32 error 487 19746 [main] sh 1212 sync_with_child: child 11816(0x720) died before initialization with status code 0x1 19941 [main] sh 1212 sync_with_child: *** child state waiting for longjmp /cygdrive/c/haskell/cygwin/usr/local/bin/haddock: Cannot fork: Resource temporarily unavailable
