Re: [STUMP] Recursive lock attempt error

[Yann Ramin]

I got this on my laptop quite a bit. I think I've managed to mask the
problem by setting the sbcl/stumpwm processor affinity to just include a
single processor. The syscall on Linux is sched_setaffinity

Interestingly, on my 8 processor workstation, I never run into this
problem. Only on the dual processor laptop. This may just be voodoo and
have nothing to do with anything :-)
