Sep 9, 2017This change removes the "static" declaration from the function slp_switch(). This forces the compiler to adhere to the ABI specification. On i386 and amd64 it is now save to configure stackless with --enable-stacklessfewerregisters, except if you compile for darwin. The flag disables explicit saving of %ebp/%rbp. On Unix-like systems the source file slp_transfer.c now gets compiled with the additional flag -fno-inline-functions instead of -O2. https://bitbucket.org/stackless-dev/stackless/issues/98 (grafted from 4f7698499ad53e5fad61fb415fbfe2c036672a9c)

This replaces the array of qbsr threads with a stack, which allows us to get rid of the stop-the-world call. There was an initialization order bug: registering a new qsbr thread might stop-the-world, but stopping the world requires the thread to already be attached! This will probably make the qsbr scan even slower, but we can improve that in the future. Fixes #97
