Update of Yandex' SMBable em driver

[Vladimir Ivanov]

Hi,

We've published latest versions at

http://people.yandex-team.ru/~wawa/em-6.7.3-yandex-1.40.tar.gz
http://people.yandex-team.ru/~wawa/em-6.9.6-RELENG7-yandex-1.36.2.8.tar.gz

These revisions use mtx_trylock instead of mtx_lock in em_start().

Regards,
