fiber/new
cfunction
(fiber/new func &opt sigmask)
Create a new fiber with function body func. Can optionally take a set
of signals to block from the current parent fiber when called. The
mask is specified as a keyword where each character is used to
indicate a signal to block. The default sigmask is :y. For example,
(fiber/new myfun :e123)
blocks error signals and user signals 1, 2 and 3. The signals are as
follows:
a - block all signals d - block debug signals e - block error
signals t - block termination signals: error + user[0-4] u - block
user signals y - block yield signals 0-9 - block a specific user
signal
The sigmask argument also can take environment flags. If any mutually
exclusive flags are present, the last flag takes precedence.
i - inherit the environment from the current fiber p - the
environment table's prototype is the current environment table
