julian b8d69589f3 Changes to the LINUX_THREADS support to only allocate extra memory for ... shared signal handling when there is shared signal handling being used. This removes the main objection to making the shared signal handling a standard ability in rfork() and friends and 'unconditionalising' this code. (i.e. the allocation of an extra 328 bytes per process). Signal handling information remains in the U area until such a time as it's reference count would be incremented to > 1. At that point a new struct is malloc'd and maintained in KVM so that it can be shared between the processes (threads) using it. A function to check the reference count and move the struct back to the U area when it drops back to 1 is also supplied. Signal information is therefore now swapable for all processes that are not sharing that information with other processes. THis should addres the concerns raised by Garrett and others.
