#10 Segfault when SMP is enabled in Erlang

[Sergei Golovan]

Hi!

Appears that applications which use esdl segfault when Erlang VM is run with SMP enabled. To reporduce the crash just run

erl -smp enable +S 2 -s erldemo go

(I've got crashes using Debian Linux on x86 and x86_64 architectures).

Since Erlang/OTP R12B-0 enables SMP by default on multicore CPU machines the issue becomes more serious than in times of R11B-*.

Esdl can't be run in smp mode, ok only with one thread, opengl requires
that all calls are from the thread that created the opengl-context, which
can not be guaranteed in erlang.
Take a look at wxerlang.sf.net project where I use a separate thread
for all opengl calls it's slower but might be good enough.
