>=20

I significantly increased CONFIG_XENO_OPT_SYS_HEAPSZ and switchtest=20
seems to me runs fine:

[root@domain.hid bin]# ./switchtest

My problem with non-RT application happens only if RT application=20
(running in the same time) uses native skin. Perl and Eclipse=20
application fails when switchbench is running, but not problems during=20
switchtest.
